How much of it down to that injury before he left?
Still, it is a shame, he was a very exciting player to watch, capable of unlocking any defence with a moment of genius or his speed.
The injury was clearly serious, but he was taken care of with Bayern's doctors/surgeon, if there was any doubt whatsoever that he would not make a full recovery, Bayern would not have completed the deal, he was given a huge contract, clubs like Bayern don't do that if there is any doubt over fitness.
He was a wonderful player, for me the most exciting to watch since the takeover and like I said earlier, for me he had all the requirements to be a world great, he simply has gone backwards, so sad to see.
