Tentative approaches have been made for Sergio Ramos, with reports suggesting he is willing to leave Real Madrid.
Speculation in Spain claims the versatile defender is furious with his current employers after they backtracked on contract promises.
Ramos believes he was entitled to a bumper pay rise this summer, but has seen fresh terms fail to materialise.
He is now prepared to consider offers from elsewhere, with numerous clubs willing to dig deep in an effort to secure his signature.
Premier League giants Chelsea and Manchester City have been linked with big-money moves, with both clubs expected to splash the cash during the transfer window.
Ramos' brother and agent Rene Ramos has revealed that interested clubs have already been in touch with Real and has refused to rule out an imminent exit from Santiago Bernabeu.
"Sergio merits better treatment at Real because of the work he has done and his quality," he said in The People.
"It is normal that his talent has been recognised by foreign clubs.
"We have received calls and inquiries but it is in the hands of Real."
