Andriy Yarmolenko's last-gasp winner in the London derby meant Chelsea failed to leapfrog Leicester City in the Premier League table on Wednesday night.

The Blues were beaten 3-2 at the London stadium as Yarmolenko's classic left-foot finish handed the east London side three points.

It looked like both sides would share the spoils but Yarmolenko’s 89th-minute goal downed the west London club.

The Hammers saw a first-half goal ruled out because Michail Antonio was deemed offside and was in Chelsea keeper Kepa Arrizabalaga's way.

Chelsea then took the lead through Willian from the penalty spot eight minutes after West Ham were denied a goal but the homeside responded with a Soucek header just at the brink of half-time.

Man-of-the-match Antonio handed West Ham the lead six minutes after the break and that goal was cancelled out when Willian's sublime free-kick found the net with 18 minutes to play.

With injury-time just around the corner, David Moyes’s boys stepped up a notch with a counter attack that saw Antonio set up Yarmolenko to hit the target with a clinical finish.

The result left Chelsea just two points clear of in-form Manchester United and Wolves who sit in fifth and sixth spot respectively in the race for a Champions League spot – with six matches left to play.

Chelsea boss Frank Lampard, speaking to BBC Sport: "We dominated the game in terms of possession, but make mistakes and teams will hurt you. I'm not happy with any of the goals. You don't get given victories for scoring two goals, you have to be better than that.

"There were moments they counter-attacked, which we knew they would. There were details in the game which we knew but we lost because we didn't get them right. Against West Ham you have to make recovery runs. That is the bit we got wrong.

"It is why we are fighting for top four not one or two, because we don't get things right as much as the big boys do. I am not happy but at the same time we are two points ahead of Manchester United, who have been going great for some time.

"If you don't get details right in big games, you're going to drop points. At times we have played really well this season. As a group we need to find more consistency."

While speaking to Sky Sports he rued his team's inconsistency and errors.

He said: "It's the story of our season. It's been a good season but there have been so many of these moments. We had an opportunity today to go through but you have to do every part of the game to get results.

"If you switch off or make one or two errors then you will encourage teams. Players have to show an extra mentality to get through these games.

"I get to see this group closely and I've seen us play great games then have moments where there's the opportunity to capitalise and that's the difference at the moment. We have work to do."

The 42-year-old continued: "There's without a doubt a good group of players in there but then when you analyse the consistency, you feel a game like this is coming. Again, that shows there's work to do.

"If we are opening up to try and score that winning goal then we have to be prepared to run back the other way and defend. And defend better.

"We are two points ahead of Manchester United, who have been playing fantastic and are on a great run, Wolves are having a great season and they're behind us, Leicester have had a great season and we're just behind them.

"It's about perspective. We are upset because we wanted to win the game, we're footballers and we're in a good position. So there's no point in being down but I can't help but say the truth today which is that it's a game we should have won tonight."
