The Portuguese central defender is desperate to link up with Real coach Jose Mourinho, who managed him at Porto before bringing him to Chelsea to 2004.

He has been one of Chelsea's key players since moving to Stamford Bridge, producing solid displays at the back along with his defensive partner John Terry.

"If there was a possibility to sign with Real Madrid, I would go there right now swimming or running," Carvalho told Spanish daily AS.

"Chelsea have a commitment with me to let me go this summer, for reasons which those responsible at the club and I know.

"With Mourinho I experienced two marvellous periods at Porto and Chelsea.

"To have the opportunity to win another Champions League with him at Real Madrid would be something tremendous."
