Arsenal came from behind to beat West Ham United 3-1 in the Premier League on Monday at the London Stadium and pick up their first win under caretaker manager Freddie Ljungberg.
The Hammers edged a poor first half and went in ahead at the break thanks to a deflected effort from Angelo Ogbonna.
Arsenal failed to clear a corner properly which allowed Pablo Fornals to cross for Ogbonna to head past Bernd Leno via a deflection off defender Ainsley Maitland-Niles.
The Gunners hit back in the second half, scoring three goals in nine minutes to secure a much-needed victory.
