We have overpaid for many other players in the 5 years as well...that's just when we had poor people in charge. In saying that, Vucinic and Quags haven't been so bad..they have contributed when they had to. Maybe inconsistent at times, but still were not a complete waste of money.
As for Nani, im not sure how he can be worth 20 million. If we could negotiate that down to 10 to 15 million, I wouldn't be upset at it.
