Former Spain coach and Real Madrid captain Fernando Hierro has paid tribute to Cristiano Ronaldo.

The former Real star hit a superb hat-trick for Juventus in their stunning Champions League win over Atletico Madrid.

"He's fantastic, as he is and as he has always been, an exemplary player, a marvel of a player without a doubt," said Hierro.

Asked if Real are missing the Portuguese, Hierro was reluctant to comment.

"I am not the one to value that, but I can say that he is a wonderful player and an extraordinary person."
