Real Madrid captain Sergio Ramos is set to return to action for the Galacticos after missing several weeks due to a niggling injury.
He is back in training and expected to be in starting lineup for the Laliga clash against Osasuna on Saturday and the second leg against Chelsea on Wednesday.
“He’s training with us and that means he’s able to play too,” Zidane told a news conference.
“We’ll see what we do when we name the squad, but Sergio is fit and ready to play.”
“LaLiga is always such a tough competition and it’ll be that way until the end,” said Zidane.
“We want to win this league title, we know it’ll be difficult but we’re going to give everything to do so until the end of the season.
“There’s obviously been a lot of games, players have had problems, but in a season all sorts of things happen. The important thing is that we’re ready to go out there and compete.”
Zidane also confirmed that Dani Carvajal, Ferland Mendy and Lucas Vasquez will miss the Osasuna clash.
