Robin van Persie wants Arsenal to prove their ambition before he pens a new contract.

The Daily Express says Van Persie has asked for firm guarantees that Arsenal are prepared to spend big, and match his ambitions, before committing his future to the club.

Arsenal have offered to increase Van Persie's salary to £65,000 a week, but the Dutchman wants £80,000.

There are also apparently fears inside the Arsenal dressing room that Real Madrid will try to steal Arsene Wenger in the summer.
