Arsenal's title hopes were dealt a major blow on Saturday afternoon as the Gunners were handed their second league defeat of the season at relegation-threatened Everton.
A second-half goal from Toffees defender James Tarkowski proved the difference between the two sides with Sean Dyche overseeing a victory in his first match in charge of the Merseyside outfit.
As for Mikel Arteta's men, they remain top of the Premier League but will hope that their north London rivals Tottenham can do them a favour on Sunday afternoon as they host Manchester City, the Gunners' nearest challengers.
