#1 Massimiliano Allegri

The perfect candidate for Arsenal, Max Allegri is a managerial genius who is all set to leave Italy and Juventus. And if the Gunners win the Europa League and qualify for the Champions League, he would definitely be interested in joining the club.
If they fail to do so, though, Allegri may still get attracted by the 'project' at hand, at the prospect of being able to build on Arsene Wenger's legacy, and at the possibility of making Arsenal top dogs again.
He's shown over his coaching career that he has both the tactical nous and the force of personality to do so, and Arsenal would be hard-pressed to find a better replacement.
Over the course of managing Aglianese, Real SPAL, Grosetto, Sassuolo, Cagliari, Milan, and Juventus he's managed a win record of 52.52% with his percentage with the Bianconeri being a reassuringly high 71.03%.
