The 24-year-old midfielder Mateo Kovacic has asked to leave Real Madrid.
Kovacic is frustrated by a lack of playing time in Real Madrid, where he has played for three seasons.
According to Spanish publication Sport, he has informed the Champions League winners that he wishes to depart.
However, Real would not appear to be too keen to let him go as they seek to keep the squad together following the arrival of new manager Julen Lopetegui.
