Turkey coach Vincenzo Montella admits Arda Guler's situation at Real Madrid is a concern.
The midfielder is struggling for minutes in his first season with Real.
Montella sees Guler as a potential key for their Euros campaign - though needs the midfielder to be playing regularly.
He confirmed: I went to see Arda. He plays very little, but I hope he can do it from now on because he has a lot of talent.
"We follow him very carefully. We will call on our players who are in their best physical condition for the Euro Cup."
