MADRID, March 28 (Xinhua) -- Spanish club Real Madrid will try to sign Manchester United winger Cristiano Ronaldo and AC Milan midfielder Kaka for next season, club president Ramon Calderon said on Tuesday.

Ronaldo is in the contract renewal talks with United, but according to some Spanish media, Real hope the Portugal international will reject the deal and leave for the Spanish club.

"We really like him (Cristiano Ronaldo) but he belongs to Manchester United and they have to decide to sell him first," Calderon said.

Calderon also said he would renew his bid to sign Brazilian midfielder Kaka from AC Milan, something he had pledged to do during last year's presidential election campaign.

"I would love to see both Kaka and Cristiano Ronaldo play for Real Madrid next season, but it won't be easy. Any big club would have this sort of objective and Real Madrid is a big club."
