"West Ham defeat Manchester United 1-0 after de Gea blunder costs Red Devils crucial points in top-four race"

Manchester United's hopes of securing a top-four finish in the Premier League have taken a hit after they lost 1-0 to West Ham at the London Stadium. 

Despite starting brightly, United were unable to capitalize on their early dominance, and David de Gea's mistake allowed Said Benrahma to score West Ham's opener. 

After the break, the Hammers looked to extend their lead, but de Gea denied Tomas Soucek and Michail Antonio had a goal ruled out. 

United failed to break down the home side's defense in the closing stages, and the defeat puts a dent in their Champions League aspirations. 

Meanwhile, West Ham's victory sees them move closer to Premier League survival, and they now sit above the relegation zone.
