The Uruguay striker has suffered a disastrous first season in Italy.
But Daniel Bolotnikov said: "Diego is happy at Inter Milan and loves the people who work for Inter. He has a contract, he wants to respect it.
"Offers from Fenerbahçe? I have read of several teams who want Diego, but no one has contacted us.
"Will Forlan remain with Inter? As I have said, he is happy to play for Inter, although he is a player who goes all out to win. Next season will be difficult, especially without the Champions League."
