Abraham holds the ball up in the corner and then knocks it behind off a Norwich defender, eating up precious seconds.
90' +2
The backtracking Kovacic makes a crucial challenge on Martin and then wins a foul from the same man. That might be enough for Chelsea.
90' +1
There will be a minimum of three minutes of added time, but the clock is running down a little too quickly for Norwich. Pukki fails to find Idah following a counter.
89'
J. Martin enters the game and replaces L. Rupp.
Before Chelsea can take their free-kick, Martin is introduced in place of Rupp.
88'
E. Buendía gets yellow.
Buendia brings Hudson-Odoi down right on the corner of the Norwich box.
James has been very lively since arriving from the bench and sends in a searching cross from the byline, which Krul gratefully watches pass straight through the box.
87'
Barkley has time and space to work an angle for a shot 25 yards out, but Klose blocks and the ball loops through to Krul. Chelsea soon have it back, though.
86'
T. Abraham enters the game and replaces O. Giroud.
Giroud's last involvement is that stabbed shot wide. He makes way for Abraham.
84'
Both Barkley and James work the ball neatly down the right for Chelsea, but Norwich belatedly stand firm. They have just been forced back a little in their pursuit of an equaliser.
82'
Now Norwich have the ball. Chelsea need desperately to hold on.
Minute
Description
81'
C. Hudson-Odoi enters the game and replaces C. Pulišić.
Pulisic is another who has impressed for Chelsea, hitting the bar and collecting an assist. Hudson-Odoi is his replacement.
80'
R. James enters the game and replaces Marcos Alonso.
Chelsea respond with a change of their own. Alonso has had a good game, but James is more defensively reliable. Azpilicueta switches to the left.
79'
M. Stiepermann enters the game and replaces A. Tettey.
T. Pukki enters the game and replaces O. Hernández.
A. Idah enters the game and replaces J. Drmić.
It is a triple-change for Norwich. The midfield is bolstered, too, as Stiepermann replaces Tettey.
Pukki also arrives in an attacking move, replacing Hernandez.
Norwich are hanging on but still believe they can get an equaliser. Idah is on for Drmic.
78'
Chelsea work the ball wonderfully from right to left, but Pulisic does not get the corner he believes he merits.
74'
Lovely close control from Barkley on the edge of the area allows him to turn and spot a pass to Pulisic, who in turn attempts to chip Giroud through on goal. The striker does not read it, though.
72'
Unorthodox from Giroud! Lewis manages only a poor clearance from Alonso's looping cross, allowing Azpilicueta to set himself and deliver again. Once more, Giroud is up highest, twisting to aim a header just over while spinning in the air.
71'
E. Buendía enters the game and replaces T. Cantwell.
Cantwell has been key when Norwich have been able to move up the pitch. He carries the ball up to the edge of the Chelsea box before slipping in Hernandez, whose attempts to dance through Chelsea challenges are not entirely successful. Aarons sees a low cross blocked and Chelsea eventually get the ball back.
Cantwell has been lively but is on a booking and now bows out, allowing Buendia to come on.
70'
Chelsea look to move through the gears coming out of the break, but their hard pressing finds no immediate reward.
68'
The game resumes after that brief stoppage.
67'
R. Barkley enters the game and replaces R. Loftus-Cheek.
The first change comes from Chelsea, with Barkley on for Loftus-Cheek.
Immediately after Barkley's introduction, there is another drinks break.
65'
Chelsea have just slowed the game again with a period of possession. Norwich are pressing, though.
63'
Norwich's latest set-piece is as harmless as the previous attempt. Chelsea clear. The hosts might yet need a second goal here, though.
62'
M. Kovačić gets yellow.
The play is pulled back for a booking for Kovacic, who lunges after Cantwell following a loose touch.
Norwich are growing in confidence! After Cantwell steals possession, Rupp looks to push forward but cannot spot a team-mate. Instead, Lewis gathers the ball and hammers in a shot that deflects over.
61'
The foul on Aarons gives Norwich a rare opportunity to get men forward for a set-piece, but Chelsea successfully defend the dead ball and then look to counter. Krul dashes from his line and hurries a hacked clearance but survives.
60'
K. Zouma gets yellow.
The second yellow card swiftly follows the first as Zouma dives in on Aarons, who knocks the ball down the line and then takes a tumble.
58'
T. Cantwell gets yellow.
Really poor challenge from Cantwell. He can have no complaints as he collects the game's first yellow card. The midfielder dances away from a couple of challenges but then loses out to Loftus-Cheek, on whom he plants a late lunge.
56'
Willian looks frustrated as his latest dazzling work down the right concludes with a cross that drifts over each of his team-mates.
55'
Chelsea are quickly back on the attack and the ball pinballs around the Norwich box. They eventually clear but Drmic cannot get close to the long ball, allowing Chelsea to build again.
Chelsea will want to be careful not to push the door too far open. They are attacking in numbers, but so too are Norwich. Azpilicueta blocks a fierce McLean drive.
54'
Crucial challenge from Rudiger! Cantwell takes the ball from Jorginho, who has had a few sloppy moments, and feeds Hernandez. A low cross evades a number of defenders, but Rudiger is there to prevent a shot on goal.
52'
Willian tears the ball from Tettey 25 yards from goal and drives forward to see a shot deflected over by Lewis.
51'
It is tough to see how Norwich might come back into this game. Their attacking threat has waned as the season has worn on, and Cantwell has no team-mate up in support as he sends a tame cross into Kepa's grateful clutches.
50'
Klose was in the wars in the first half, dealing with a knee issue, and now he is slow to get back to his feet after taking a whack to the head from Giroud. The striker is winning that duel.
48'
Willian stays patient as he retains the ball just outside the Norwich box, but Chelsea eventually go backwards for Rudiger to thump an overhit cross behind from deep.
47'
Chelsea steal back possession on the edge of the Norwich box and Willian can win a corner down the right.
Rudiger misses the target by a long way! The defender finds space to meet Willian's corner but gets no direction on his header whatsoever, blasting an effort high into the empty stands.
46'
KICK-OFF: Chelsea's goalscorer Giroud gets the second half started!
45' +4
HALF-TIME: Chelsea 1-0 Norwich City
45' +3
O. Giroud has scored a goal for Chelsea! Assist by C. Pulišić.
GOOAAALLLL!!! GIROUD FINDS HIS RANGE! 1-0 Chelsea! After a couple of disappointing mishits, Giroud makes the most of a big opportunity. Pulisic delivers a gorgeous cross, and Giroud brushes off the challenge of Klose to head past Krul.
It is a wonderful assist from Pulisic just moments after an Alonso cross towards Giroud is well defended. Azpilicueta complains of contact as he tussles for the initial cross but is back on his feet to see Giroud head in.
45' +1
There will be a minimum of three minutes of added time at the end of this goalless first half.
45'
Norwich give the ball up a little cheaply in their own half as Willian steals in, and the Brazilian gets down the right. A low cross deflects but lands harmlessly in the arms of Krul.
44'
Willian is hobbling. He darts back to foul Hernandez after the Norwich winger cuts out Kovacic's pass. Norwich are still getting players forward into attacking areas wherever possible.
43'
Kovacic is involved in some neat build-up play on the left, but Giroud's flick is wayward as Chelsea move the ball inside. McLean then wins a free-kick from Pulisic as Norwich regroup.
41'
Giroud has had a few opportunities but still has not caught a shot sweetly. He holds off the challenges of Klose and Tettey in the area but, still stuck in a crowd of Norwich players, stabs awkwardly well off target. Krul intercepts.
40'
Norwich again deal with a corner. It has been slightly desperate stuff at times, but they remain level.
39'
Alonso is keen to have a go at every opportunity. He whips in a cross-cum-shot from Willian's lay-off, but Cantwell's slight touch carries the ball beyond both the goal and the waiting Chelsea players.
38'
Chelsea are now boasting possession in more dangerous areas and have players queuing up in the centre as Alonso's cross is deflected behind. The subsequent corner is cleared by Aarons, though.
37'
Willian now races to the byline to keep the ball in play and cross, but Godfrey is across to clear. Norwich are hanging on a little all of a sudden.
WIDE! Close for Zouma! From the corner after Krul denies Pulisic, Zouma is up highest but nods just wide. The pressure is mounting.
35'
Almost a chance again! Chelsea force a corner on the left, which Willian delivers. Azpilicueta flicks the ball on at the near post and the ball drops just beyond the far. Loftus-Cheek keeps the play alive with a header, but there is no blue shirt on hand to turn the ball goalwards.
34'
Norwich survive! Chelsea work the ball really smartly initially, with Alonso's low cross finding Giroud, who flicks the ball across goal from his position at the near post. Willian almost gets a toe to the ball, but a defender blocks, before Giroud's right-footed cross is nodded away.
28'
Norwich are frustrated as Rupp gets no free-kick after he goes down on halfway. Chelsea can attack instead.
27'
Drmic is really lacking support as he gets a first opportunity to run at Chelsea. Jorginho loses possession on halfway, but Drmic has only Cantwell to his right and nobody ahead of him. He fails to outrun Alonso.
26'
The game gets back under way with a Norwich free-kick, and Hernandez works hard to force a rushed Chelsea clearance and keep his side on the attack.
24'
The drinks break comes with the game still goalless. Norwich have been on the backfoot but might well be happy with how the game has gone so far.
22'
It is Chelsea pass after Chelsea pass at the moment. Norwich are pressing up to the halfway line right now, though, forcing them back.
19'
Lampard might be slightly concerned that Chelsea are struggling to break down Norwich despite their possession. Given their recent problems in defence, he would have hoped for a swift breakthrough.
18'
Alonso manages to beat the offside trap and get on the end of a ball lofted into the area. He struggles to control first time, though, and Kovacic handles as Norwich attempt to clear.
16'
Vital challenge from Godfrey! The centre-back intervenes in the nick of time as Pulisic swipes at the ball inside the area, leaving both players limping. Alonso lashes well, well wide from outside the area.
15'
In a rare Norwich foray, Lewis is again the man to get forward, crossing down the left. Cantwell cannot quite get in front of Alonso to meet a teasing delivery, before Aarons sends in a second centre which Chelsea deal with comfortably.
12'
Azpilicueta just runs out of space under pressure from Lewis at the byline, giving Norwich some respite in the form of a goal-kick.
10'
Both Loftus-Cheek and Rupp are able to get up and continue after a strong challenge in the centre of the pitch. Chelsea have the ball once more.
9'
There is effort and energy from Norwich, but Chelsea are swarming all over their lowly opponents. This is one-way traffic so far.
7'
Norwich attempt a rare attack down the left through Lewis, but Azpilicueta blocks the cross. Willian instead advances at the other end, forcing Klose to cover for his full-back. A smart block concedes only a throw-in.
6'
Chelsea's first corner does not get past the near post as Norwich head clear, yet Cantwell soon concedes a foul as the visitors attempt to counter.
5'
Chelsea are settling into a spell of possession now. The ball goes out to Alonso on the left, but a powerful low cross evades everyone, although Chelsea still keep the ball.
Azpilicueta tries to be a little cuter on the right as he gets to the byline and then cuts a pass back to Loftus-Cheek. A subsequent cross is deflected behind. Corner.
3'
Willian gets his first opportunity to run at the Norwich defence. His pass is cut out, but Chelsea quickly win the ball back and remain on the attack on the right flank.
Wide from Loftus-Cheek! The midfielder is unmarked as he advances to meet Azpilicueta's low cross with a header. But the Chelsea man is past the near post and cannot direct the ball on target.
2'
Good defending by Zouma. Cantwell cuts out a pass and prods the ball down the right for Rupp, yet Zouma is first across and shields the ball behind to win a goal-kick.
1'
KICK-OFF: After all 22 players take a knee, Rupp gets us under way for Norwich!
Norwich may be playing for little more than pride now, but they are straight on the attack and snap into a couple of early challenges when Chelsea recover the ball.
Hello and welcome to our live text commentary of the Premier League clash between Chelsea and Norwich City!
Chelsea suffered a major setback in the race for Champions League qualification as they were humbled by Sheffield United on Saturday. But top-four rivals Leicester City and Manchester United both also dropped points later in the weekend, meaning the Blues improbably remain third with three matches to play.
There is no room for a further slip-up against already-relegated Norwich, though. Chelsea must still face Liverpool and Wolves after first this match and then their FA Cup semi-final against United.
Let's get the team news from Stamford Bridge...
Norwich City (4-1-4-1): Tim Krul; Max Aarons, Ben Godfrey, Timm Klose, Jamal Lewis; Alex Tettey; Onel Hernandez, Kenny McLean, Lukas Rupp, Todd Cantwell; Josip Drmic.
Subs: Willy Caballero, Andreas Christensen, Ross Barkley, Tammy Abraham, Pedro, Mason Mount, Callum Hudson-Odoi, Reece James, Fikayo Tomori.
Chelsea (4-3-3): Kepa Arrizabalaga; Cesar Azpilicueta, Antonio Rudiger, Kurt Zouma, Marcos Alonso; Ruben Loftus-Cheek, Jorginho, Mateo Kovacic; Willian, Olivier Giroud, Christian Pulisic.
Subs: Michael McGovern, Mario Vrancic, Emi Buendia, Marco Stiepermann, Tom Trybull, Teemu Pukki, Adam Idah, Jordan Thomas, Josh Martin.
That's all from this one. Thanks for joining us for a narrow, much-needed Chelsea win. Until next time, goodbye!
Third-placed Chelsea move four points clear of Leicester and Man United, although both have an extra game to play. There is still work to do against Liverpool and Wolves. Norwich's time in the Premier League winds down against Burnley and Manchester City.
