WATCH: David de Gea's Costly Blunder Adds to Man United's Woes in Defeat to West Ham

A David de Gea blunder allowed West Ham to take the lead against Manchester United as Said Benrahma's long range shot managed to slip into the net.

Benrahma charged towards the United goal and unleashed an effort from outside the box. De Gea dived low to stop it and got a touch to the ball, but it somehow slipped beyond him and into the net, making it 1-0 after 27 minutes. That goal ended up being the difference between the two sides, and United are now only one point clear of fifth-placed Liverpool with a game in hand.

 De Gea's error comes in a milestone appearance for the Spain international, who has now featured 540 times for United, more than any goalkeeper in the club's history. It is just the latest mistake from the 32-year-old, however, as it comes in the wake of his horrific performance against Sevilla, which saw United crash out of the Europa League. Even that game was followed by a shaky display in the previous round against Real Betis.

However, it has not all been bad for the shot-stopper, as he put in a solid performance against Brighton in United's FA Cup semi-final victory. Meanwhile, it has been reported that he is set to agree a contract extension with the Red Devils, with his current deal set to expire this year.

De Gea's mistake against West Ham was his fourth error leading to a goal of the 2022-23 campaign - the joint most from any player in the Premier League alongside Tottenham's Hugo Lloris.

De Gea will hope to avoid any further mistakes when United welcome Wolves to Old Trafford on May 13.
