Arsenal fear Mathieu Flamini is stalling on their contract offer so he can set up a lucrative move in the summer.
The Frenchman, 23, has been a revelation alongside Cesc Fabregas in midfield this season.
But Flamini's contract is up in June and he has still not signed a fresh five-year deal offered more than a month ago, says The Sun.
The Gunners could double his wages to £40,000 per week but he may prefer a move to Spain or Italy.
