It is no coincidence that Arsenals upturn in form has coincided with some of Jack Wilsheres best performances. The central midfielder has been at the heart of everything good at Arsenal this season and his ability to dictate in games has seen the Gunners dominate possession in almost all of their fixtures. Wilshere has also added a strong running game to his appearances this season, with his driving runs out of midfield becoming a key aspect of his performances, however Arsenal fans got a firm remainder of the England stars fragile nature at the weekend as he limped off during the Gunners' win over Sunderland. Wenger must keep the Arsenal star fit if they are to achieve Champions League qualification, because quite frankly, the North London side just arent the same without their midfield maestro.
