Real Madrid coach Zinedine Zidane admits Eden Hazard is frustrated with his injury problems.

For victory over Real Valladolid, Hazard was in the stands at the Estadio Alfredo Di Stefano, with the Belgian out for another few weeks with injury.

"It's muscular," Zidane explained.

"Apart from his injury, he's just fine.

"I can't say how long he will be out for sure.

"It was like a muscle contraction, but not much more than that.

"It can happen.

"He's annoyed because he was fine [before]."
