But Roeder has insisted the former Galatasaray and Inter Milan star, a £4million signing during Graeme Souness' time on Tyneside, will be going nowhere.
Roeder: "Where this story has mushroomed from, I have no idea. Like I have with all the senior players, I have got an excellent relationship with Emre.
"I am not aware of Bayern Munich making any offers for him whatsoever and I certainly would not encourage them, or any other team, making offers for him.
"He is very much part of my plans. He's a hugely talented, technical player, I think he is a player the fans enjoy watching at St James' Park.
"Graeme Souness was right when Emre came here - Inter Milan do not keep players for four seasons if they are not of Champions League standard. He's certainly a big-game player on the big stage.
"Normally, there are no secrets in football - you normally hear what the jungle drums are bashing out. But it is better to stamp this out now so it does not run and run."
