Mikel Arteta shook things up against Chelsea to get Arsenal back on track in the Premier League title race and in doing so may have unlocked a new winning formula.
In the four games prior to Tuesday night's London derby, the Gunners hadn't tasted victory. Three draws against Liverpool, West Ham United and Southampton followed by a 4-1 loss away at Manchester City have caused them to stumble at the worst possible time in the season.
But Arteta's side aren't down and out just yet. If the win over the Blues proved anything it's that the players have not given up hope of being crowned Premier League champions, although beating Newcastle United on Sunday afternoon is key to keeping those hopes alive.
