Marcel Sabitzer is aware Manchester United are interested in Eintracht Frankfurt centre-forward Randal Kolo Muani.
However, the Bayern Munich loanee says he hasn't been in contact with the France international.
He told Sky Deutschland: "I know him and he is a very good player. But I am not involved in transfer activities.
"I can only say what kind of player he is. He has taken an incredible step this year.
"So it is clear that many clubs are interested."
