Leeds United boss Jesse Marsch admits an approach has been received for Mateusz Klich.
The midfielder is being linked with a MLS move this week.
Marsch said today: "There has been inquiry in Mateusz, but from all sides we are still cautious about thinking whether it is time for him to leave.
"He has been really important here; one of the interesting things is he has played the fifth most games for me since I've been here; 25 of 28 games.
"He is one of my favourite personalities I've ever coached. We've been honest with each other along the way. I'm not sure it is the time for him to leave."
