Perfectionist Antonio Conte told man-of-the-match N'Golo Kante to cut out the mistakes.

Kante put in another commanding midfield performance in the 2-1 win at West Ham as Chelsea re-established their 10-point lead at the top of the Premier League.

He made an astonishing 50 passes, of which just five did not find their intended target.

He committed more fouls in the first-half than Chelsea did as an entire team, which rather sums his performance up. AFP/Getty Images West Ham vs Chelsea player ratings Winston Reid – 6 out of 10 Made two crucial first-half interceptions and proved more solid than the decidedly erratic Jose Fonte. Getty Images West Ham vs Chelsea player ratings Jose Fonte – 4 out of 10 The winter signing struggled against Chelsea’s pace and made two first-half howlers: first doing too much on the ball and dribbling into trouble, then suffering the indignity of an air-kick as he went to boot the ball away from Pedro. Spurned two good goal-scoring opportunities in the second-half.

Their partnership shows promise. Put some good balls into the box for Carroll to contest but exposed defensively by Hazard. . Getty Images West Ham vs Chelsea player ratings Mark Noble – 5 out of 10 Struggled. The West Ham captain is too frequently overran in the big games. Lacked the pace to compete with Chelsea’s scampering midfield and offered little going forward. West Ham United via Getty Images West Ham vs Chelsea player ratings Pedro Obiang – 6 out of 10 One of West Ham’s better players but he won’t want to see Chelsea’s second goal again: a Cesc Fabregas corner skimming off the top of his head and into the path of Diego Costa for the easiest of close-range finishes. AFP/Getty Images West Ham vs Chelsea player ratings Sofiane Feghouli – 6 out of 10 Started the game impressively and initially looked to have Alonso’s number, showing promise in the final third. But faded as the game went on. West Ham United via Getty Images West Ham vs Chelsea player ratings Manuel Lanzini – 7 out of 10 Took his late goal very well, firing past Courtois after being played in by Ayew. A talented, but ultimately limited to a role on the periphery tonight. West Ham United via Getty Images West Ham vs Chelsea player ratings Robert Snodgrass – 6 out of 10 Made some impressive darting runs behind Victor Moses and worked nicely with Cresswell but will be disappointed he didn’t stretch the Chelsea defence more. West Ham United via Getty Images West Ham vs Chelsea player ratings Andy Carroll – 6 out of 10 A hard-working performance but Carroll, rushed back from injury for this game, never looked a threat unless the ball was in the air. Even then, he was well dealt with by Cahill and David Luiz. West Ham United via Getty Images West Ham vs Chelsea player ratings Thibaut Courtois – 7 out of 10 Rarely called into action but did well against the aerial threat of Andy Carroll. Made a fine save to keep Jose Fonte out. Getty Images West Ham vs Chelsea player ratings Cesar Azpilicueta – 6 out of 10 The Spaniard had been identified as a potential weak link before the match but was rarely troubled. West Ham United via Getty Images West Ham vs Chelsea player ratings Gary Cahill – 7 out of 10 Another solid performance from Chelsea’s skipper. Won an impressive 5 aerial battles and made two significant interceptions. West Ham United via Getty Images West Ham vs Chelsea player ratings David Luiz – 7 out of 10 Looked confident playing alongside Cahill and also dealt with Carroll well, frequently drifting into Azpilicueta’s territory to ensure the forward didn’t isolate his smaller team-mate. West Ham United via Getty Images West Ham vs Chelsea player ratings Victor Moses – 6 out of 10 The wing-back — a revelation this season — has looked a little tired in recent weeks and was again below-par for the league leaders. It may be time for Antonio Conte to give him a brief rest. Getty Images West Ham vs Chelsea player ratings N’Golo Kante – 7 out of 10 Not the Frenchman’s finest performance but he was still a menace in the middle of the park, winning four tackles and joining the counter attack whenever possible. West Ham United via Getty Images West Ham vs Chelsea player ratings Cesc Fabregas – 7 out of 10 Another encouraging performance from the midfielder which suggests he has truly revolutionised his game under Antonio Conte. No player ran further and his through-balls proved a constant threat. West Ham United via Getty Images West Ham vs Chelsea player ratings Marcos Alonso – 7 out of 10 Restricted to just the one barnstorming run forward this week. Feghouli made a bright start down his flank but Alonso quickly recovered and kept him quiet for the rest of the evening. Getty Images West Ham vs Chelsea player ratings Pedro – 7 out of 10 Looked very dangerous on the counter-attack and combined well with Eden Hazard. Should have done better with a first-half chance though, which was deflected clear by Obiang. Getty Images West Ham vs Chelsea player ratings Eden Hazard – 9 out of 10 Brilliant against Swansea last week and tonight he was once again Chelsea’s most dangerous player. Took his goal with confidence and was a frequent menace on the counter-attack. West Ham United via Getty Images West Ham vs Chelsea player ratings Diego Costa – 7 out of 10 An almost anonymous first-half during which he only touched the ball 24 times, but what does that matter when he got his name onto the scoresheet?

But Blues boss Conte smiled: "He made five mistakes. He has to improve in this. He has to improve.

"I am joking. But I have to find one situation to tell him to improve. He's playing really well.

"He has great stamina, great quality and we are working to improve that quality. I'm pleased for him, but all my players performed very well."

Chelsea weathered a mild West Ham storm in the opening 25 minutes before Kante helped carve the hosts open in 10 seconds.

That was as long as it took for the Frenchman to intercept a loose pass near his own penalty area, and Eden Hazard to find the net in a lightning counter-attack.

Diego Costa grabbed the second from a corner five minutes into the second half, and Chelsea looked comfortable until Manuel Lanzini pulled one back in added time.

Yet even that consolation goal irked Conte, although he was delighted his players responded to weekend wins by nearest challengers Tottenham and Manchester City in kind.

"It's a pity to give away a second clean sheet at the end of the game, the second after Arsenal," added the Italian. "We must work a bit on this aspect.

"But I'm pleased for my players. It was not easy, to play after your opponents and know they won. If you drop points you give hope to your opponents in the chase. We played under pressure and our answer was very good."

Mercifully there was no repeat of the crowd disorder which marred the last time these sides met at the London Stadium, in the EFL Cup in October.

However, one fan did climb over the advertising hoardings to confront Hazard and his team-mates as they celebrated the first goal before being restrained by stewards in another worrying security breach for stadium bosses.

Hammers manager Slaven Bilic felt his side contributed to their own downfall.

"I'm really happy with the way we started," he said. "And then we made that mistake.

"It was a mistake you might be able to do against some teams. But you can't do it against them with the pace and quality they have. They don't miss that kind of thing."
