From what I've read on redcafe his injuries are really causing him problems and he might not be able to recover from them - a four year deal when you turn 32 next month and aren't sure how fit you will be to play anyway might seem like too good an offer to turn down.Such a decline in his career
He was outstanding at Arsenal and for a couple of seasons and utd.
Why any decent footballer would want to play in Turkey while still fairly young is beyond me.
