Zidane made his mark by making changes to the Los Blancos starting XI for his 150th game in charge of the club, including Keylor Navas in place of Thibaut Courtois, and starting the much maligned Isco.
The Spanish giants face Celta Vigo on Saturday and the Real Madrid boss has sparked a discussion over his starting XI.
Courtois was the biggest surprise, given he was bought by Madrid for around 40 million euros ($45 million) last summer and had established himself ahead of Navas under Santiago Solari.
Previous managers this season, Julen Lopetegui and Santi Solari, had tried to begin the process of rejuvenating the squad, benching players who have formed a key part of Madrid's core in recent years, most notably Marcelo, Isco and Gareth Bale. Zidane lost faith in Bale last season, with the pair's relationship growing increasingly strained before Zidane announced his departure.
Since the end of his first period in charge, Real's success has somewhat faltered, with the holders being knocked out of the Champions League by Ajax at home and trailing Barcelona in La Liga.
