Werder Bremen general manager Klaus Allofs has admitted he is expecting to receive offers from a number of clubs for in-demand playmaker Mesut Ozil - but has claimed there have been no concrete bids yet.
Bremen, who must qualify for next season's Champions League, are eager to renegotiate Ozil's contract, which expires in 12 months time.
But they look set to face a tough decision if he opts to hold out, with the three London clubs to have qualified for Europe's top competition - Spurs, Arsenal, and Chelsea - all expected to express an interest in the player.
Allofs is already playing hardball, however, saying he would rather risk losing the player on a free next summer than compromising on a price for the 21-year-old during the current transfer window.
"Now he is playing a fantastic World Cup campaign, there is definitely increasing interest," Allofs told German newspaper Bild.
"But when it comes down to concrete bids, nothing has been done. We want him to stay on and actually there is no news.
"There are no indications he does not want to see out his contract at our club."
Ozil has emerged as one of Germany's leading lights at the World Cup - pulling the strings for the national team in much the same way as he already does for his club side.
And Werder chief Allofs said he is determined to keep the current squad together to reach the lucrative group phase of the world's premiere club competition.
"We need to have success on the field, especially in Champions League qualification," he added.
"For this we need to have a good team."
