Manchester United should do everything to secure Real Madrid defender Sergio Ramos.

That is the opinion of former Newcastle United goalkeeper Shaka Hislop.

34-year-old Ramos could transform the club's defence in the same way Edinson Cavani has improved their attack.

Ramos could be a free agent in the summer if he cannot agree to a new contract with Real Madrid.

"Yeah why not? I'll tell you what, I'm hugely impressed with Cavani," Hislop said.

"I didn't think Cavani would be as good or as impactful as he has been.

"Sergio Ramos coming in at the other end of the pitch could probably have a similar effect."
