West Ham United stunned Premier League leaders Chelsea with a 3-2 victory after coming from behind twice before substitute Arthur Masuaku won it late on.
Chelsea had seemed to be in control of the game after 28 minutes when Thiago Silva scored with a header from a Mason Mount corner.
But the European champions allowed the hosts back into the game in the 40th minute when Jorginho put his goalkeeper Edouard Mendy under pressure with a poor back pass and Mendy brought down Jarrod Bowen for a penalty that was converted by Lanzini.
It took Chelsea only four minutes to get back in front when Mount connected with a floated pass from Hakim Ziyech for a perfect volley that caught out Fabianski at his near post.
But West Ham drew level again in the 56th minute when Bowen fired in hard and low from the edge of the box.
Masuaku turned the game West Ham’s way in the 87th minute when he caught out Mendy with what looked like a cross, but the ball flew into the top corner at the near post.
The win ensures the Hammers will remain in the top four whatever happens elsewhere in the Premier League this weekend.
