Zidane hopes Eden Hazard returns in the next 2-3 weeks.
The Belgian international joined Los Blancos in the summer of 2019 and has failed to live up to his potential due to injuries and fitness issues.
The 30-year old winger recently picked up an injury and is a major doubt for Madrid’s Champions League last-16 tie with Atalanta.
“It’s not an easy time for the footballer. I’m sure it’s a matter of time before we see him back playing and hopefully he won’t pick up another injury,” Zidane said at a press conference.
“Hopefully, when he recovers, we see the best Hazard, maybe in two or three weeks when he recovers.
“I think it’s a bit of bad luck. It’s not been easy on the player. We have to maintain a positive attitude. He’s a great player, we need him back 100 per cent.
“Do you think he’s happy with what’s going on? Well, no. He’s doing what he can to be in good shape, but you know in the life of a player you can be injured.
“We’ll have to look at maybe changing something and improve this situation. He’s the first player who wants to be fine, of course.”
