Zinedine Zidane said he was going to rotate his squad and he wasn't lying.
Real Madrid Starting XI: Casilla, Carvajal, Pepe, Nacho, Arbeloa, Casemiro, Isco, James, Lucas Vázquez, Jesé, Cristiano Ronaldo.
Eibar Starting XI: To Be Confirmed
It makes sense to rest the Starting XI ahead of Tuesday's difficult match against Wolfsburg, but it would have made sense to sit Cristiano Ronaldo as well.
Jesé and Lucas Vázquez will have a good chance to prove they're ready to compete, and so will Isco and James, although Zidane's choice for Tuesday's lineup seems fairly obvious after seeing which players didn't make the Starting XI today.
It will be important for Madrid to play with composure even knowing what's ahead in the schedule, as a big win today could also help the atmosphere next Tuesday. However, if Madrid struggle against Eibar, the fans will be too anxious to properly support the team on their quest against Wolfsburg.
