Arsenal were outplayed by Crystal Palace on Monday night as the Eagles went on to secure an impressive 3-0 victory at Selhurst Park.
The defeat means that the Gunners currently occupy fifth position in the Premier League, as north London rivals Tottenham Hotspur sit in fourth on goal difference. Mikel Arteta's side do have a game in hand on the Lilywhites, but they'll need to get back to winning ways against Brighton this weekend.
Whilst Arsenal do have the advantage in the race for Champions League football, they've been shocked by two major injury blows at a critical stage of the season. Kieran Tierney has been ruled out for the remainder of the campaign as a result of a knee injury that requires surgery. Meanwhile, Thomas Partey is now a doubt for Brighton following a thigh issue he picked up against Palace.
