If Klopp can't challenge for a title he'll be out, and he won't get a decade to get things right. So let's not pretend Wenger and Klopp can be compared. Klopp might fail, Wenger already has. Klopp might succeed, Wenger has no chance. Wenger can only ever be defended by looking at each of his fucked-up seasons in isolation. String them together and you see what an epic failure and a laughing stock the bloke is. Far bigger a fool than Klopp, or just about any other manager, could be.
