Ronaldo’s Handball At The Nitto ATP Finals!

Football superstar watches Djokovic beat Isner

Football superstar Cristiano Ronaldo had a strong Sunday, scoring his first goal at the famous San Siro for Juventus against A.C. Milan. But Monday was special, too, as the Portuguese sat front row at The O2 to watch World No. 1 Novak Djokovic beat American John Isner in straight sets at the Nitto ATP Finals.

“I had colours of his club on my attire tonight,” joked Djokovic, who was wearing black and white. “I'm sure he was happy to see that.”

It’s not the first time that Ronaldo has watched Djokovic or any professional tennis in person. Last year, the football player was in attendance when Rafael Nadal beat Djokovic in the semi-finals of the Mutua Madrid Open. He even got into the action in London on Monday evening when a ball bounced into the stands.

“It's great to have big football star, sports star like him, courtside watching tennis. He used to come and watch a lot in Madrid. Rafa, of course, Roger, myself. He's a fan of tennis. It's really, really nice,” Djokovic said. “He's one of the biggest sports stars in the last decade. It's great for our sport to have him there. I saw he was there with his family. Didn't get a chance to see him after the match, but hopefully I'll have that chance maybe later this week.”

Djokovic will be back in action on Wednesday, when he faces Alexander Zverev. The German defeated Marin Cilic earlier on Monday in the first match of Group Guga Kuerten play.
