"I'm so proud to play for this club not just because of who they are, but for what they have done for me personally, also I love the fans and they have been fantastic".
Ronaldo's return boosts Real's attack after a disappointing 1-1 draw at home to Levante on Saturday, their second successive home draw which left them trailing early Liga leaders Barcelona and Real Sociedad by four points.
Zidane admitted that his side face a slight problem in the absence of Karim Benzema for a period of four to six weeks, leaving the Real boss with only one recognised striker in Borja Mayoral after the club sanctioned the departures in the summer of Álvaro Morata and Mariano. He's young, he's eager and he's hungry.
Ronaldo was dismissed during the first leg of its Supercopa de Espana triumph over Barcelona and received a five-match ban for shoving the referee. "We will get through with the players we have and everything will be all right, I'm sure of that". We are all happy that he is with us. He will play tomorrow but we'll be without him again on Sunday.
"And we are happy too, because he is mentally very well, physically very fine".
The coach said that Ronaldo was focused on the task ahead and was very happy to have the opportunity to play again.
Ronaldo, who was the top goalscorer in Europe's elite competition last season for the fifth consecutive year and scored twice in the 4-1 win over Juventus in the final, has been starved of football so far this season due to a long suspension.
