Barcelona risk blowing up their locker room with an amazing offer to Real Madrid midfielder Isco.

Barca chiefs have been laying the groundwork for the sensational move since the New Year.

And with Isco still expressing doubts about his future in Madrid, the Catalans have stepped up talks in the past week with his representatives.

About to enter the final year of his current deal, Isco has made it clear he wants playing guarantees before considering new contract talks.

Don Balon says Barca have relayed their offer to the Spain international - a proposal which is sure to rock the locker room.

It's suggested the contract tabled would make him the highest paid Spaniard in the Barca squad, placing him above Gerard Pique, Andres Iniesta and Sergi Busquets.
