I wonder if Van der Sar had a word aswell. If Stekelenburg wants to move to a top 6 PL club then Edwin might have advised him that Fulham would be a good stepping stone to get there.
What exactly is so funny about it anyway? Stekelenburg is a really good goalkeeper, and the only reason people wanted him was probably because of his experience. Signing him entailed a much smaller risk than De Gea at the time because of De Gea's age and nationality - although no one ever questioned his class.
