Kaf, they don't like him anymore >> they don't want him anymore >> this guy won't play anymore in Fenerbahce>>Fenerbahce will "sell" him to another club. If they "sell "him, they won't say he is a goat.
But they still may recommend him to another club, as they don't want to pay a lot of money monthly to this player anymore, moreover transfers from one club to another does that the club who will "buy" the guy will have to pay as much as it is possible to pay for him.
Sport is business now, one buys and one sells, the one who sells has to say he sells "good stuff"
"letter of recommendation" doesn't mean they are going to overpraise him either, but they will at least say he played in their club from [mm/dd/yyyy] to [mm/dd/yyyy] and is now free from any other contract with Fenerbahce.

To be consensual, I'd say :
"Le joueur serbe Mateja kezman, tombé en disgrâce auprès du Fenerbahce, a annoncé qu'il se rendrait en Turquie cette semaine pour demander un document attestant de son emploi par le club au sein de l'équipe."
On fait comme ça Miss? kafetzou?
