The La Liga giants are having a terrible time while trying to retain their title as they sit third in the league table - 10 points behind leaders Barcelona.

Zidane’s side face Apoel in the Champions League tonight (7.45pm) and Benzema is expected to lead the line, despite only scoring two goals in 13 games.

Cristiano Ronaldo has also come under scrutiny for not being at his dazzling best.

In his pre-match press conference, Zidane acknowledged that Benzema has to do more to end his six-match goalless drought.

"He [Benzema] is the first one who knows he can give more, because of the confidence issue, especially his confidence in front of goal,” Zidane said.

"Strikers maybe need goals for confidence, but he's playing well, the team is playing well.

"When one goes in more can follow. Let's hope tomorrow [Tuesday] is the day to end the streak."

Youngsters Theo Hernandez, Marcos Llorente, Dani Ceballos and Borja Mayoral have been kept largely on the fringes of the first team.

But Zidane is not aware of any of them having a problem with him, insisting that they are simply experiencing a learning curve.

"That [those players' happiness] is a question for the players," Zidane added. 

"As far as I'm concerned, I sit down and chat with players. They're here, they're young.

"They have to work hard, but look at the rise of Marco Asensio, for example. He played less last season, but more this season.

"Ceballos is in a similar position. There are maybe a few players who play less, but it's a learning curve.

"It's normal that they play less than other squad players. But Dani and the other young players all have big futures here."
