Real Madrid are battling to secure Isco to a new contract.

Real have opened talks with Isco's minders about a new deal, but the midfielder is stalling, says Don Balon.

Isco is happy with the terms on offer, but is demanding playing guarantees - particularly with offers also arriving from England.

Manchester United and Tottenham are in contact and can guarantee the Spain international a regular start.

Isco has also been linked with a sensational move to Barcelona this summer.
