The away side looked the more likely to score and were unfortunate not to get on the score sheet before Ben Chilwell received a second yellow in the 73rd minute.
Here, we rate the Chelsea players.
THIBAUT COURTOIS: Despite Chelsea being under pressure from Leicester over periods in the first half in particular, the Belgian didn’t really have a save to make. 6
CESAR AZPILICUETA: Had his hands full with the likes of Jamie Vardy and Riyad Mahrez but did well to keep up and didn’t put a foot wrong. 7
GARY CAHILL: Struggled with Vardy’s pace and movement early on. Pulled his hamstring and had to be replaced after 33 minutes. 5
ANTONIO RUDIGER: A bit clumsy in a tackle, especially when trying to contain Mahrez but didn’t do too much wrong, was good in the air and made a few clearances. 7
VICTOR MOSES: Provided plenty of width down the right and managed to get a couple of shots away as well. 7
TIEMOUE BAKAYOKO: Didn’t have his shooting boots on but insisted on having a go more times (3) than any other Chelsea player anyway and was wayward at best. Was better at breaking down a few Leicester attacks though. 6
N’GOLO KANTE: Was buzzing against his former side, driving forward and making some good tackles as well. Was in danger of being a little too enthusiastic though and was walking a tightrope after his booking. 7
CESC FABREGAS: He wasn’t at his best in terms of passing, providing just one key pass and registering an accuracy of 76.9%. His best moment was a shot from distance which was tipped over the bar. Was replaced in the 58th minute. 5
MARCOS ALONSO: Had one good effort from a free-kick at the death but contributed little other wise. 6
EDEN HAZARD: Was excellent at the start and had Leicester players falling over themselves but couldn’t find a killer pass and managed just one shot. Was hauled off before the hour mark as he began to fade. 6
ALVARO MORATA: Another disappointing performance. Had one good run in the first half when he did well to win a corner. Other than that, his touch was poor and decision-making just as bad. Couldn’t register a single shot throughout the game. 4
ANDREAS CHRISTENSEN (for Cahill 33′): Replaced Cahill in the first half and was solid. Did well not be lured into a challenge when Mahrez tried to win a penalty off him. 7
PEDRO (for Fabregas 58′): Couldn’t affect the game enough. Had one shot at goal but didn’t look threatening. 5
WILLIAN (for Hazard 58′): Looked like one of the players who could snatch something for the hosts but wasn’t to be. 6
Lacazette hit the ground running following his £50million move from Lyon last summer, netting four times in his opening six league fixtures for Arsenal.
But the France international, 26, has now gone nearly 10 hours without finding the back of the net – he last scored in the 3-1 defeat against Manchester United at the beginning of December – and he was largely ineffectual in the Carabao Cup semi-final at Chelsea before he was substituted in the second half.
Lacazette, however, is likely to be given another chance to recapture his early-season form when Arsenal travel to Bournemouth in the Premier League on Sunday.
Wenger could be without Mesut Ozil as he battles a knee issue, while the ongoing uncertainty over Alexis Sanchez‘s future may result in him being unavailable. Olivier Giroud, who has been sidelined since Arsenal’s EFL Cup win over West Ham last month with a hamstring injury, will also be absent for a further fortnight.
“(The lack of goals) certainly affects him (Lacazette) a little bit, but I am not worried,” Wenger said. “He was diminished a bit physically on Wednesday night against Chelsea because he was not at his best before the game, but he was as well very isolated.
“It was a difficult game for a striker because he did defend a lot, but overall I don’t worry that he will come back and it’s in cycles. At the moment he’s going through a cycle that is a bit more frustrating for him.”
Arsenal return to Bournemouth for the first time since their thrilling 3-3 draw on the south coast last season.
Wenger’s side were left stunned as the hosts raced into a three-goal lead, but the Gunners completed a dramatic comeback when Giroud netted a stoppage-time equaliser.
Bournemouth have won only one of their last 10 matches in the Premier League and have slipped to 16th.
But Wenger is anticipating a tough time of it from Eddie Howe’s team as Arsenal bid to get their top-four ambitions back on track.
“Last year was a spectacular game, where it finished 3-3,” Wenger added. “Basically what can happen in the story of a game is that you can go through all kind of states of mind – the nightmare, the relief and then the frustration – because we could have won the game in the end.
“They are a team who have a bit more difficulty this season but down there they can make it difficult for anybody.
“The league is divided into two now. As long as we have a group of seven or eight teams fighting for the top four, the rest are basically fighting to stay in the league, and as long as the positions are not settled, every game will be a cup tie.”
Here are five talking points leading into the game.
CAN LIVERPOOL END CITY’S UNBEATEN RUN?
Liverpool’s recent form suggests they have a better chance than most sides of late of ending that sequence.
With their much-vaunted attack and high-pressing game, the Reds are unlikely to sit back and that could make for a compelling encounter.
Liverpool may be warned, however. The last team to really try to get after City was Tottenham on December 16, and they were swatted aside 4-1.
Liverpool also fared badly last time the sides met – losing 5-0 at the Etihad Stadium in September – but City have not won at Anfield since 2003.
STERLING’S ANFIELD RETURN
Since leaving Liverpool in 2015, Raheem Sterling has enjoyed little good fortune against his old club.
He was booed and substituted at half-time on a quiet first return to Anfield in March 2016 while he was also ineffective in that year’s League Cup final.
This time the 23-year-old will hope things will be different as he goes back to his old stomping ground in the best form of his career.
With just over half of the season gone, Sterling already has 18 goals to his name this term – seven more than his previous best return.
AGUERO ON SONG
The Argentinian, who was being criticised as recently as Christmas for lacking sharpness, has scored four in his last three games and now has 19 for a season in which he became City’s record goalscorer.
He has scored six times in 14 games against Liverpool.
VAN DIJK LEAGUE DEBUT
Liverpool’s £75million man Virgil van Dijk is poised to make his Premier League debut for the Reds.
His impact has already been impressive, with a debut winner against Everton in the FA Cup.
The Dutchman brings leadership, composure and greater defensive ability to to side badly short in those areas. Liverpool look stronger for his arrival.
His departure will leave a hole but Jurgen Klopp is not short of other attacking options with Adam Lallana now fit again and Alex Oxlade-Chamberlain looking to step up.
The game will offer clues as to whether the Merseysiders can move on seamlessly.
