Navas kept a clean sheet as Zidane's side secured a 2-0 victory at home to Celta Vigo.
Zidane lost faith in Bale last season, with the pair's relationship growing increasingly strained before Zidane announced his departure. Looks like it could be a two-man job with Modric and Kroos and Isco as a number 10.
From out of the wilderness, Isco and Marcelo featured from the off. Isco was making his first league start since Julen Lopetegui's final match at the helm - the 5-1 defeat at Barcelona in October - while Marcelo was enjoying just his fourth league start of 2019.
Gareth Bale also makes the team, while out of favour left-back Marcelo is also included.
The Frenchman led Madrid to three consecutive Champions League titles before surprising the football world by handing in his resignation. I am going to count on them.
It was one of three tackles he made - more than any other Real player - and it was this dogged determination in defence, as much as his well-taken goal in the second half, which outlined his desire to play for a team he has always been linked away from.
"Marcelo has not played much, that is true, but he is a professional and he has been very good in season".
Real were knocked out of the Champions League at the last-16 stage by Ajax.
Zidane has also made a big call in goal, with Courtois dropping to the bench after a 4-1 comeback win at Real Valladolid last week and Costa Rica worldwide Keylor Navas recalled.
"There's so many factors you need to think about when you sign players".
