Jarrod Bowen insists West Ham "never know when we are beaten" after the Hammers came back from behind to earn a shock 3-2 victory over London rivals Chelsea on Saturday.

Chelsea twice took the lead in the first half through Thiago Silva and Mason Mount, but Manuel Lanzini and Bowen netted equalisers before Arthur Masuaku's cross caught Edouard Mendy out at his near post and won the game for West Ham.

Bowen explained the Hammers pride themselves on their spirit and never-say-die attitude - which has helped them to fourth in the Premier League this season.

"That is what we are about as a team, the character, the belief," Bowen said to BT Sport after the game. "We hung in sometimes when it was difficult.

"We never know when we are beaten, we went behind twice but showed that reaction and a lot better performance.

"We wanted to be on the front foot and press them aggressively and not let them play, which they are good at. We wanted to limit what their game plan was.

"We haven't won in a few games and have been disappointed in ourselves, but to come back and beat Chelsea, what a performance."

West Ham manager David Moyes was critical of his side's performance despite the positive result, but praised the clinical finishing of his team, who scored three times from just five shots on target.

"Truthfully, I didn't think we played that well today," Moyes said. "But we got the goals and in other games I don't think we played any worse or any better but we haven't got the goals.

"Today we got the goals to go with it, and to get them against a team that don't concede many is a great credit to the lads.

"We were much better [in the second half]. We were too passive and submissive in the first half.

"They are quality, that is why they are European champions because of the level they can play at. Whether you press them or stay off them, they are very good at both."

Moyes felt Masuaku was attempting to cross the ball and was lucky to see it go in for the first Premier League goal of his career.

"I said to [Masuaku] that I thought it was a great cross," Moyes added. "It was very fortunate, the goal, but in football you need a bit of fortune sometimes. In the last few games we have lost it a little bit, but today we got it back."
