Following the game, Zidane says that the problem is not a major one - but it does leave question marks over his condition with the trip to Kiev to face Liverpool just two weeks away.
The Spaniard played a vital role for Madrid in Sunday's El Classico 2-2 draw leading Real Madrid twice coming from behind to deny Barca an outright win at the Camp Nou. "But a draw also isn't a bad result for us given how the game went".
Cristiano Ronaldo departed Real Madrid's Clasico clash with Barcelona at half-time after picking up what appeared to be an ankle injury, but Zinedine Zidane expects him to be available for a Champions League final date with Liverpool.
"We always respect Barcelona but in that play I thought kicking the ball out was not necessary".
The 33-year-old looked in discomfort but continued for the rest of the half, only to be replaced by Marco Asensio at the start of the second period. The Camp Nou erupted in applause and acknowledged the contributions of a living legend when he was substituted, reminding everyone that there would only be one Don Andres.
FW Lionel Messi, 8 - Only the Argentine is capable of the skill and shooting ability he demonstrated for his goal, fending off Sergio Ramos and Casemiro before rifling into the bottom corner. It was clear that Marcelo baited him into lashing out, and baited the referee into showing a red card. In the build-up to Barcelona's second goal, Suarez blatantly brought Raphael Varane down, but the referee waved play on.
Lionel Messi scored a mesmerising, record-extending 26th goal in the Clasico to put 10-man Barca back in front after 52 minutes. "We had a lot of chances".
Zidane, however, insisted Madrid's players will not form an honor guard for Barcelona because Barcelona's players didn't honor Madrid after it won the Club World Cup in December.
Alaves routed Malaga 3-0, and Getafe beat Las Palmas 1-0.
