Arsenal missed the chance to leap above rivals Tottenham and go third in the table as they went down 1-0 to Everton at Goodison Park on Sunday.
Phil Jagielka - who was only called into the starting lineup by Marco Silva at the 11th hour after Michael Keane fell ill - scored the only goal of the game after just 10 minutes following Arsenal's inability to clear a Lucas Digne throw.
The defeat sees the Gunners stay in fourth place, with all four top four contenders now having played 32 matches.
The Gunners are a point behind Tottenham , who weren't in action this weekend, and level on points with Chelsea, who face West Ham at Stamford Bridge on Monday night.
