Arsenal missed the chance to return to the top of the Premier League as they slipped to a disappointing defeat to West Ham amid more VAR controversy.
The Gunners needed victory to replace Liverpool at the summit but lost 2-0 on a night where Hammers boss David Moyes finally landed a victory at the Emirates Stadium.
West Ham lost Kurt Zouma ahead of the game and Lucas Paqueta after just over half an hour but hit the front through Tomas Soucek’s strike, awarded after VAR could not determine whether the whole ball had gone out of play in the build-up.
A second-half header from former Arsenal defender Konstantinos Mavropanos secured the points and things could have been even better for the visitors had Said Benrahma not seen a last-gasp penalty saved by David Raya.
