“Barcelona and Manchester United are huge clubs. It would be difficult to turn them down. I have not said anything and there is nothing to talk about, but, of course, if Barcelona made an offer I would have to consider it,” Calhanoglu told Turkish broadcasters Lig TV, as quoted by the Evening Standard.
Bayer want at least £32 million for the Turkish international playmaker and he still has another three-years left on his contract.
Calhanoglu has been closely linked with Barcelona and Manchester United over recent weeks with the Bild claiming that the Red Devils sent scouts to the last match between Roma and Bayer a fortnight ago.
The 21-year-old still has three-years left on his contract and Bayer CEO Michael Schade recently revealed that the club would only listen to offers of £28.9 million and above.
The Turkish international already has six goals and four assists to his name this season and has established a name for himself as a free-kick maestro. The Bayer playmaker already has 22 goals from direct-free kicks to his name.
