18. Nils Petersen
Every now and then a new player comes along who is supposed to be soccer’s next big thing. Enter Petersen. It might seem crazy now, but this man was one of German football’s great hopes during his time at Energie Cottbus. Needless to say, Bayern Munich snapped him up as soon as he became available.

Petersen wasn’t ready to play at the highest level. He was unable to handle the pressure and hadn’t developed enough to threaten for a starting place in the squad. First-team opportunities were few and far between. Overall, his signing was a total failure. He’s currently with Freiburg as his reputation faded away.
