Do you think Thomas Muller could be worlds best in a few years to come?

In Germany's first game of the WC against Australia i watched Thomas Muller play instead of the game itself and he played really well IMO and had a feeling he would be really good and decided to really like him and tell everyone he was the best, but I kept watching Germany's games and Muller just kept scoring and now he's won golden boot. Easily the third best thing to happen in my life but still after Ballack he is def favourite player now :D I regret not putting money on him though the odds would have been nuts at the start :I
