Hazard has endured an injury-plagued time at Madrid since his £89million move from Chelsea in 2019, but will be in squad for Tuesday’s clash after making his comeback from a latest muscle problem in Saturday’s 0-0 draw with Real Betis.
Zidane confirmed: “He played 15-20 minutes the other day and was quite good. The most important thing is that he didn’t feel anything after about his problem.
“He is happy because he is going to contribute to the team a lot.”
Real teammate Raphael Varane added: “I have talked to him, he is quite motivated to play in a Champions League semi-final. It motivates any football player and if you play against a former club, I believe that’s an extra motivation.
“We know the quality he has and he wants to prove that on the pitch and help the team.”
Real’s preparations for tomorrow’s game have been overshadowed by their involvement in the failed European Super League plans.
There have been suggestions they could even be kicked out of this season’s Champions League as punishment.
But Zidane said: “It is absurd to think that we are not going to be in the Champions League next year. That’s it – everything has been said.”

The Real manager was full of praise of Thomas Tuchel’s impact at Chelsea, adding: “It’s a semi-final, of course it is going to be a complex match. The most difficult match is the next match.
“I don’t think it is going to be a closed game, Chelsea is a complete team. They defend properly and they attack properly.
“We need to pay attention and when we create opportunities like we have been doing, we need to see our best version so can hurt Chelsea.”
