Cristiano Ronaldo dined out in London after taking in Novak Djokovic's sensational performance courtside at the ATP World Tour Finals.

The 33-year-old took in the Serb's straight sets victory over John Isner at The O2 Arena alongside partner Georgina Rodriguez and son Cristiano Jr.

The Juventus superstar was later spotted at the exclusive Novikov Restaurant in Mayfair.

Ronaldo scored the second in the 2-0 win over AC Milan on Sunday to secure an unprecedented 34 points from 36 points available after 12 games in Serie A.

The Portuguese was forced to step in and restrain Gonzalo Higuain however, with tempers spilling over when the Argentinian was sent off against his former club.

"I told him [Higuain] to calm down, as he risked an even worse ban," Ronaldo told Sky Sport Italia.

"He didn't do much, he was annoyed at losing the game. That's understandable. I hope he is not punished too severely.

"I'm happy. We won, and it was fundamental with Napoli beating Genoa yesterday.

"We played well, I also scored... I'm really happy to help the Juventus family. Good team performance, against a difficult Milan."
