David Moyes says West Ham will have to win all four of the remaining Premier League games to beat Chelsea to a place in the Champions League.
The Hammers returned to winning ways after coming from behind against Burnley at Turf Moor thanks to two goals from Michail Antonio on his return.
West Ham now sit three points behind fourth-placed Chelsea with four games to play - against Everton, Brighton, West Brom and Southampton.
While he was delighted with the result, Moyes said they'll have to end the season with five straight wins to overcome the Blues.
"I'd love to be in Europe," Moyes told Sky Sports.
"It would be an incredible achievement. We're not far away from the Champions League positions. We've got to keep believing.
"Four games to go, it's great. I want to smile about it. I've been here before - we'll probably have to win the four games. If we played the way we played tonight we'll give most teams a game."
