Arsenal missed an opportunity to reclaim the top spot in the Premier League, suffering a disappointing defeat to West Ham amidst further VAR controversy.

The Gunners aimed for victory to surpass Liverpool at the summit but lost 2-0, with Hammers manager David Moyes securing a rare victory at the Emirates Stadium.

Despite losing Kurt Zouma and Lucas Paqueta to injuries, West Ham took the lead through Tomas Soucek's strike. The goal was awarded after VAR could not definitively determine whether the entire ball had gone out of play in the build-up.

A second-half header from former Arsenal defender Konstantinos Mavropanos secured the points for West Ham, and the visitors could have extended their lead further if not for David Raya saving Said Benrahma's last-minute penalty.

David Moyes secured a long-awaited victory in his 73rd Premier League away game at Arsenal, Chelsea, Liverpool, or Manchester United as West Ham defeated Arsenal 2-0. The win denied Arsenal the chance to return to the top of the table.

Arsenal struggled to continue their recent winning streak in London derbies, with only captain Martin Odegaard standing out. Despite a strong start from Arsenal, defensive lapses allowed West Ham's Tomas Soucek to score, with VAR unable to conclusively determine if the ball had gone out of play in the build-up.

Arsenal's efforts to equalize were in vain, with Gabriel Jesus missing key chances. Konstantinos Mavropanos, a former Arsenal player, extended West Ham's lead with a second-half header. Despite a late penalty opportunity for West Ham, Arsenal's David Raya saved Said Benrahma's spot-kick.

The defeat marked a forgettable night for Arsenal, while Moyes celebrated a significant away win.
