Manchester United suffered a major setback in their quest for a top-four finish as they slumped to a 1-0 defeat at West Ham, with goalkeeper David de Gea making a costly error. The Spaniard allowed a weak shot from Said Benrahma to slip through his fingers and into the net, leaving his teammates stunned and struggling to regain their composure.

This latest away loss marks the eighth of the season for United and raises questions about their ability to maintain their focus during the crucial stages of the campaign.

Here's a look at how the United players fared at the London Stadium.

Goalkeeper & Defence

David de Gea | GK | 2.9/10

Once again, the Spanish goalkeeper's poor form let Manchester United down. De Gea should have saved Benrahma's weak shot, and his passing put his teammates under unnecessary pressure throughout the match.

Aaron Wan-Bissaka | RB | 7.2/10

Wan-Bissaka impressed with his one-on-one defending and tactical fouls. He was booked for only the second time this season, a testament to his perfectly timed challenges and defensive awareness.

Victor Lindelof | RCB | 5/10

The Swedish defender was not as dominant as in previous matches, and was fortunate not to give away a penalty for a handball before halftime.

Luke Shaw | LCB | 5/10

Playing out of position at centre-back, Shaw struggled against Benrahma but cannot be blamed for De Gea's error.

Tyrell Malacia | LB | 5/10

The Dutchman was unimpressive going forward and looked shaky defensively.

Midfield

Christian Eriksen | CM | 6/10

The Danish midfielder provided more control than Fred, but struggled in the second half.

Casemiro | DM | 4.9/10

The experienced Brazilian midfielder made many poor passes and lost the midfield battle to Declan Rice.

Bruno Fernandes | CM | 6/10

Fernandes was one of United's better players, comfortable in a box-to-box role, but needed to offer more in attack.

Attack

Antony | RW | 6/10

The Brazilian winger was bright in the first half, unlucky not to score, but missed two other good chances and faded in the second half.

Wout Weghorst | ST | 5/10

The Dutchman made his first start in eight games, worked hard defensively, but offered little in attack.

Marcus Rashford | LW | 6/10

Rashford played well, hitting the woodwork and looking like United's only threat in the second half. However, his form is dipping at a crucial stage of the season.

Substitutes

Anthony Martial | ST | 6/10

The Frenchman offered more than Weghorst, nearly equalizing with some fine movement, but missed a good header from a corner in added time.

Marcel Sabitzer | AM | 6/10

The Austrian was unable to make an impact when he came on.

Jadon Sancho | RW | 4.9/10

Sancho's cameo was another disappointment.

Diogo Dalot | RB | N/A

The Portuguese right-back was introduced in the final minutes of the match.

Fred | CM | N/A

The Brazilian was also introduced in the final minutes.
