Zidane admitted that his team would have to up their game if they wanted to overcome Gremio in Saturday's final.
"We are going to try to improve," he said.
"That's clear, because they are a physical, technical team, and stronger than Al Jazira.
"We're convinced of playing a better match with the ball and in all other aspects."
"Everyone can say he was a good player," Zidane noted.
"But I don't share that, because for me Cristiano is much better."
