Arsenal, Tottenham and Manchester United target Nadiem Amiri has a €17m (£15m) release clause, according to Sport Bild.
The Sun reported last month that the Hoffenheim playmaker was being pursued by the Gunners but Bild believe that Spurs are the team who are the most interested in the 21 year old.
Amiri has recently separated from his agent Gordon Stipic and is now advised by his brother, and it seems the midfielder is now pushing for a transfer.
The German Under 21 international turned down overtures from other clubs to sign a new three year contract back in June, but the existence of the buyout clause means Hoffenheim are resigned to losing him, either in January or in the summer.
Amiri has had a decent season in the Bundesliga, having scored four goals and provided two assists in 19 appearances. He has yet to reach his prime, and is believed to have huge potential which the Gunners, Spurs and United believe could make him a star of the future.
