Ronaldo has trained with the first team squad as normal this week and could be given the chance to hone his sharpness against Villarreal, in Real’s final league game of the season.
Real can still snatch second place from Atletico Madrid if they win and Atletico lose at home to Eibar on Sunday but Zidane’s players will be keener to make their case for a starting spot against Liverpool.
Gareth Bale, in particular, will be under scrutiny, with the Welshman’s place far from secure despite his man-of-the-match performance against Celta Vigo last weekend.
Bale scored two excellent goals in the victory but Zidane twice dodged the chance to say his display will influence his thinking.
“You can say he’s better because of the goals he has scored, but he has been training well,” Zidane said.
“The most important thing is to see everyone in good physical shape. That’s what I care about.”
