Two-time champions Madrid will face Emirati outfit Al Jazira in Wednesday’s semi-final at Zayed Sports City Stadium in Abu Dhabi.
And Madrid are keen to secure their third title of the season, having already claimed the UEFA Super Cup and Supercopa de Espana.
“It will not be easy and last year we had a lot of problems before we managed to win it,” Zidane said.
“There will not be easy games and for just being Real Madrid we are not going to win. We have time to prepare for the game and there are no excuses.
“It is normal that during the season you have ups and downs but what we have done so far is very positive. We have won two titles and we are trying to win a third.
