The wild card I think is how fast can Van Gaal put Man U back together playing his style. I am a Gunners fan and thus despise Man U; but, they have the talent and money. I see them making a late charge at the end of the season. Liverpool spends the entire year trying to figure out how to replace Jaw's goal production.
My top 5 - Chelsea, Man City, Arsenal, Man U, Liverpool.
Oh, and of course, Tottenham Hotspur ends up relegated. LOL. Actually, I can see Southampton having issues after their apparent fire sale.
