Cup finals can throw up surprises, last season's looked like it might do that until Hull collapsed. However, I can't really see past Arsenal for this one, they look as good as I can remember for many seasons at the moment. Possibly Villa's 6-1 thrashing at Souhampton and the home defeat to Burnley could be partly put down to the players having one eye on this game. However, not exactly the form to make you think the Villans can do the business at Wembley.
