Leandro Trossard's goal secured a narrow 1-0 win for Arsenal over Everton and ended a run of four straight defeats at Goodison Park.
It wasn't a straightforward affair for the Gunners as they had to dig deep to overcome a VAR drama in the early exchanges.
Gabriel Martinelli's sweeping finish put Arsenal in front in the first first-half, only for VAR to rule out the goal as Eddie Nketiah was found to be fractionally offside in the build up, despite the ball only reaching him via a heavy deflection off Everton striker Beto.
But the Gunners emerged from the interval on the front foot and were rewarded with a well-deserved goal in the 69th minute.
Trossard, who came on for the injured Martinelli in the first-half, fired a first-time finish in off the post from Bukayo Saka's pass following a smartly-worked corner.
The goal marked his first Premier League goal of the season and eventually clinched a long-awaited victory for Mikel Arteta's side.
Arsenal move up to fourth while Sean Dyche side's are rooted in 18th position and wait for their first league win of the season.
