Wenger insists today's trip to Wigan will not be a pushover for the Gunners. And he has tipped Latics boss Martinez to one day manage a top-four team.
He said: "Roberto finds something every year when everybody writes them off. He finds the resources to get results nobody expected." "The club was at Highbury with no training ground and 80 employees. Today we are nearly 500 staff in a big stadium and have a big training centre. We are a world-known club. We have been consistent at the top level."
