Tottenham are expected to move for Mainz 05 attacker Yunus Malli in the coming days.
The 24 year-old midfielder's contract carries a €10 million buyout clause - which expires on July 31.
BILD says Spurs are keen on Malli and could meet his escape option this week.
Asked about the situation, Malli refused to shut down the speculation yesterday: "I cannot and will not rule anything out.
"What is the point when I say now I will play this season for Mainz, and then in two weeks it looks different?
"If there is nothing else, that's fine. I feel so comfortable here, we'll play in the Euro League."
