I would say either Arsenal or Liverpool for the title this season. Both are long overdue.
Arsenal though, are lacking in firepower up front and don't seem to be making any significant moves in the transfer market to bolster their squad. Injuries to their key players will see them falter. Liverpool have built up a good squad of players and they did it early in the transfer window, hopefully allowing them adequate time to gel. The problem with Balotelli last season was that he was signed too late and was more of a distress purchase. Like when you go to the 24 hour garage to buy flowers for SWMBO's birthday and end up with a gallon of Castrol and some spark plugs instead.
Man City have a formidable attack and will probably play with three up front from the start. Chelsea shouldn't be discounted either.
