"I don't want to get involved," the former Chelsea manager told Sky Sports News.
"If one day Didier has a clear situation in his life with his club - which is a club I love - and he is on his way out and I am Inter coach, Gamba Osaka coach, Red Bulls coach or whatever coach, everyone knows he's one of my men.
"He's one of my men. Whatever club I am at the door is always open for him.
"But he's a Chelsea player, a very good player - and at the moment there's 0% chance of him coming to Inter in January."
