When van der Vaart broke through in Ajax I thought he was utter brilliant. I was sure he'd become a Ballon d'Or winner at some point in the future. He's looked anything but that ever since though. His career has been extremely disappointing. The quality is still there but he's getting old. If Wenger can get the potential out he's probably a good replacement for Rosicky. Who knows, Rosicky could even be moved further up the field whenever he's back. I can see this happening. Not for £11 million though.
