Arsenal target Julian Draxler insists he is happy at Schalke, but has not ruled out a move away from the German side.
Draxler was pursued by Gunners boss Arsene Wenger in January but the Frenchman would not match the £37 million release clause in his contract.
The 20-year-old midfielder's contract expires in 2018 but the German international insisted his release clause was good for the club and himself.
He told Sky Sports: “I extended my contract because I feel good here.
“It is no secret that I have a release clause, which of course leaves much room for speculation but it is also good for both parties.
“It's good for Schalke because the club will not sell me below this amount and good for me because I can make my own decision if a club decides to pay the money.”
Draxler's Schalke take on Real Madrid in the first leg of their Champions League last 16 tie tonight and are the fourth German club in action in the round.
Last week, Bayer Leverkusen lost 4-0 at home to Paris Saint-Germain while Bayern Munich won 2-0 aganst Arsenal at the Emirates, and last night Borussia Dortmund won 4-2 at Russian side Zenit.
