Whilst I agree that he has the right to earn as much as he can during a limited playing career, in terms of time, the point, I think, that others are making is that with a professional footballer is that it is not always about money.
Ericksen could of gone to Man City but chose not to, because in his own words;
"“Manchester City really wanted to sign me last summer but it didn’t feel right. I didn’t want to go to a club just to stay on the bench."
Even though he would/could of earned much more than at Spurs.
