Jose Mourinho has warned potential Bundesliga suitors not to pick up Belgian starlet Kevin De Bruyne for a song.
De Bruyne has struggled to make an impact since his arrival from Genk in the summer and his agent reportedly said the player would welcome a return to German football, where he was on loan at Werder Bremen.
The Chelsea boss says he does not want the 22-year-old to leave, but admits the midfielder has not quite adapted to the special pressures of playing for Chelsea.
“We know Kevin didn't adapt very well to the difficult life a Chelsea player has, which is to pay a big price to play,” Mourinho said.
“They have to give a lot, to work a lot and to accept competitiveness. He was a very important player for Genk and for Werder Bremen. It's the first time he comes to a big club with big competition.
“He is a fantastic player with fantastic potential, but it's a bit difficult to adapt to this situation, so we know that he fancies a move.”
Mourinho added: “I don't want him to leave. We've had a couple of contacts, not by us because we don't want to sell, but made by other clubs.
“But he is a fantastic player and fantastic players are very expensive, so if people think they can get our good players on sales, the sales finished at 11 last night.”
