Enzo Maresca says he is "not concerned" by his team committing errors leading to goals this season after Chelsea came from behind to beat West Ham 2-1.

Levi Colwill played a blind backpass to Jarrod Bowen, who duly scored the opener for West Ham just before half-time.

However, Pedro Neto equalised before an Aaron Wan-Bissaka own goal clinched the points for the Blues, moving them up to fourth in the Premier League table.

Only Southampton (17) and Aston Villa (11) have made more errors leading to goals in the top-flight this season than Chelsea's 10.

The hosts also won a Premier League game at Stamford Bridge in which they had trailed at half-time for the first time since December 2013 against Southampton (3-1), with this the 18th game since (D2 L15).

Maresca was pleased with the fight his team showed, especially after West Ham took on a more defensive approach.

"Today was a tough game, especially mentally," Maresca told BBC MOTD. "When West Ham come here and sit back with 10 players behind the ball, it's not easy, so you have to be mentally strong, and you need to be patient.

"We had more than 10 shots in the first half. We had clear chances in the first half, but unfortunately, we missed the target. With some changes, the game completely changed. Overall, we completely deserved to win the game.

"I'm not concerned [about the errors], it's the way we play. Sometimes, defensive mistakes happen. A keeper mistake, number nine misses the goal. That's football. It happens. The important thing is to continue.

"It was a good weekend for us in terms of results [Manchester City and Newcastle United both lost] and we knew today was even better."

West Ham, meanwhile, fell to a third defeat under Graham Potter, who became the ninth former Chelsea manager to have taken charge against the Blues at Stamford Bridge without winning.

One bonus for the Hammers was the return of Bowen, who was back in the starting line-up earlier than expected after recovering from a foot injury.

Only against Wolves (seven) and Newcastle United (six) has he been involved in more Premier League goals than against Chelsea (four – two goals, two assists).

Potter was delighted with his captain's impact but was also left frustrated as he felt the first Chelsea goal should not have counted due to a shove by Colwill by Bowen earlier in the move.

"I thought the performance was really good, lots of good things," Potter told BBC MOTD. "I thought we were intelligent tactically.

"We felt a little bit unlucky with the first goal, we thought there might have been a foul leading up to it. Sometimes you need those things to go your way, but it wasn't meant to be.

"We could have nicked a point with Mo [Kudus, who saw a late chance blocked], and I think we would have deserved that.

"Jarrod Bowen was fantastic, he led the team, and it was a proper captain's performance. You see the players that we've got and the spirit there. We can be positive for the future."
