I voted yes, but really it depends.... wouldn't want him massively unbalancing our wage structure and unsettling the current squad for that reason. Also wouldn't want him to be a guaranteed starter every game at the expense of one of our young attacking maestros. No question he'd be a massive upgrade on Kone or Naismith though - and would generate tons of publicity (hopefully for all the right reasons).
Everton is in his blood as much as any of us and I reckon he massively regrets some of the stunts he pulled when he left. Would be happy to see him make up for it by playing with passion and driving the team to trophy-winning form. It seems obvious to me that he's not going to do that at Utd, so why not here?
