Ronaldo netted his 23rd goal in 12 games and at one point earned applause from the home supporters at the Juventus Stadium - for his incredible overhead-kick that made it 2-0 on the evening in the high profile UEFA Champions League quarter-final tie.
Zidane admitted after the game that the 33-year-old is in the form of his life and Los Blancos are reaping the rewards - but cheekily suggested his goal in the 2002 Champions League final against Bayer Leverkusen was a superior effort.
"It's what Cristiano can do. He is going through a good spell and we are taking full advantage of that. It's a good night and we have to enjoy it," he said, as quoted by AS.
"Cristiano's is one of the best goals in history, but mine in Glasgow was prettier. You have to tip your hat to a goal of this quality.
"He does so many things and I'm happy for what he's achieved," Zidane added, as quoted by Marca. "I'm a Real Madrid coach, but I'm a football fan too. And when I see that goal, it's just a natural gift."
