Plus any of our real top players will only ever be sold to one of the real big boys eg Real/Bayern. They don't tend to spend big money on players unless they are almost/are the finished article. Bergvall is having a great first season, but is a long way from being there. Unless something crazy happens he will be here for another 3/4 years minimum I would imagine....They got their way because they had a year left on their contract. Kane found out that if you have a long contract you won't get your way.
Bergvall comes across as sensible. He's better off staying where he is and developing. He knows he'll get game time. Either way he won't have a chocie for another couple of years.
