why Berbatov and Rooney are switching roles

For the last 2 season Wayne Rooney has been the golden boy of Manchester, and Dimitar Berbatov has been given the name Berbaflop, it finally looks like roles have reversed, and it shows how the reward of effort finally looks to have paid off, so while Rooney has late night sessions in dodgy hotel, Berbatov has lost weight and gained an even better first touch, the price tag now looks justified and the only question now has to be when will Rooney get back to the level he was at last season.
