Juan Roman Riquelme is playing hardball with Villarreal over his move to Boca Juniors.

The Argie is demanding pay-out of his contract before agreeing to join Boca and warned yesterday: "It's up to the club to solve this situation. I have a contract with them until the year 2009 and there is no problem, but I want to receive everything I'm owed.

"If they respect me until the last euro of the contract that I have in Spain, then I'll return to Boca without problems."
