Arsenal legend George Graham feels their top four hopes can only be strengthened by Jack Wilshere's return.

Wilshere was in superb form until he suffered the injury in March and Graham thinks the Gunners will only get stronger when the England star returns.

"Jack Wilshere is one of the few world-class players in the team," Graham said. "He was out for so long and they missed him.

"He's not only got wonderful technical ability, but he's a natural winner. They need that drive from midfield, without question."
