Freddie Ljungberg recorded his first victory as manager of Arsenal as the Gunners came from behind to beat their host West Ham United 3-1 on Monday night.
Arsenal scored three quick goals within nine minutes to record their first victory in ten matches at the London Stadium on Monday.
West Ham's first meaningful possession produced the game's first meaningful chance in the 5th minute as Felipe Anderson picked it up in bags of space between the lines and feeds Antonio. His shot from the edge of the box was a little wild.
Arsenal started defending poorly and dangerously. First, it was a West Ham player brought down inside the box in the 22nd minute, but the Gunners were able to escape without a VAR check.
Three minutes later another foul was committed at the edge of the box when Robert Snodgrass got booked by Mike Dean following his late sliding challenge on Gabriel Martinelli, but West Ham saw their cross defended away by their visitors.
Before the half-hour mark, Arsenal suffered an injury blow when Tierney went down injured inside the Gunnera box having dislocated his shoulder, he could not continue play and was replaced with Sead Kolasinac.
West Ham broke the deadlock in the 38th minute when Angelo Ogbonna's header, off a Pablo Fornals' pass, was deflected by Ainsley Maitland-Niles into his net. VAR was called in to confirm the goal and it stands.
Five minutes extra time was added but the first half ended 1-0 in favour of West Ham United.
After the restart, Cresswell's evening was done in the 51st minute as Masuaku came on to replace the full-back.
West Ham then attacked the right flank before the ball was cut back for Declan Rice, whose first-time drive from 25 yards was hit with plenty of power but it was curled straight at Bernd Leno.
Arsenal drew level on the hour-mark Sead Kolasinac attacked the left flank and his cut-back into the box was latched onto by an unmarked Gabriel Martinelli, who tucked home his first Premier League goal into the bottom corner.
Six minutes later, Arsenal took the lead when Nicolas Pepe's left-foot shot curled into the top corner of the net.
The goal rush continued with West Ham now crumbling. Pepe's chipped ball into the box saw Pierre-Emerick Aubameyang volley home past Martin.
Few minutes later, Arsenal nearly made it four. Martinelli cutting the ball back for Lucas Torreira, whose rising drive was well blocked.
As the game entered its final minutes, Pepe was released on goal again and he looked to have the pace on Ogbonna. But he curiously cut inside and ended up losing the ball.
At the end of 90 minute regulation time and seven extra minutes added, West Ham fans began to leave the stadium as they gave up hope of a possible comeback. Yes, they were right as the game ended 3-1 to Arsenal.
