West Ham United secured a home Premier League victory over Manchester United for the third straight year thanks to second half Crysencio Summerville and Jarrod Bowen goals on Sunday.
The visitors had their chances to open the scoring in the opening period, but it was Summerville who struck first 16 minutes from time, prompting late drama as both sides had their moments.
Alejandro Garnacho struck the crossbar after being set-up by Bruno Fernandes inside two minutes, while Łukasz Fabiański had to make saves from Rasmus Højlund and Casemiro.
The Red Devils were punished for those misses when half-time sub Summerville snuck in around the back to finish off from Danny Ings' touch and net his first goal in Claret and Blue.
However, just seven minutes later the visitors were level when Casemiro was left free in the middle to nod home after Diogo Dalot kept a deep Amad cross alive at the far post.
The drama continued though as the Hammers were awarded a stoppage time penalty for a Matthijs de Ligt foul on Ings after a VAR check, and Jarrod Bowen stepped up to strike home into the bottom right corner.
