Ronaldo left Real Madrid on Tuesday after nine years, to play for Juventus on a four-year deal, with his transfer fee said to be worth over AUD $135 million.

The Italian club will also pay additional $19 million as part of FIFA's solidarity mechanism.

"I said that Cristiano would stay because it was my desire," said Modric, who is set to captain Croatia in Monday morning's final against France.

"Cristiano is unique and it's a shame he leaves. I wish him well, except when he plays against Madrid. I appreciate everything he did for Madrid," added the midfielder.

Ronaldo is Real's all-time top scorer, netting 451 goals in 438 matches for the club. He won the Champions League four times with Real and was twice crowned La Liga champion.

He scored four goals at the World Cup in Russia before reigning European champions Portugal crashed out of the tournament after losing 2-1 to Uruguay in the Round of 16.
