Premier League leader Arsenal was surprised (1-0) at Everton, remobilized by the arrival of Sean Dyche on his bench on Saturday for the 22nd day of the Premier League. The Gunners, with 50 points, are still five ahead of their immediate pursuer Manchester City. The two teams have the same number of matches, but the defending champions will play Tottenham on Sunday to go back perhaps two lengths. This almost unexpected success, but generally deserved, is only the fourth this season for the Toffees who temporarily come out of the red zone by climbing to 17th place with 18 points.
