Not in contractual terms.... but not very good example to use as a pro footballer, no? Was offered to several clubs, he wanted his wages to stay the same and the buying club could not afford £40K a week at the time, and Chelsea could not afford to subsidise it. A few deals didn't go through because of his wages demand. So not good in footballing terms, but great for his bank account surely....Don't see what he has done wrong though - Chelsea gave him a contract and he upheld his side of it.
Not his fault he wasn't as good as Chelsea thought he would be.
