The future of Manchester City defender Ko Itakura is far from being decided.
The Japan international has spent the season on-loan with Schalke 04, where he is wanted in a permanent deal.
However, Sky Deutschland says Eintracht Frankfurt and SC Freiburg are also interested in Itakura.
The 25 year-old can stay with S04 for a fee of €5.5m, but they must sell first before dealing in the player.
The permanent option expires in June.
