WATCH: Cristiano Ronaldo jumps on Chinese police officer as fan invades Juve training

Cristiano Ronaldo appeared to take liberties when he jumped onto a Chinese policeman at a Juventus training session as officers rushed to deal with a fan who had charged onto the pitch.

The local interrupted Juve's session at the Nanjing Olympic Stadium, where they are preparing to face Italian rivals Inter Milan in the International Champions Cup on Wednesday.

The excited supporter was quickly chased down by officers wielding batons as Juventus players watched on.

Ronaldo then jokingly jumped on top of one blue-shirted officer, who turned with a quizzical look before waving the footballer away.

The fan was then escorted away having come within touching distance of his footballing idols. 

During Juve’s last game against Tottenham in Singapore on Sunday, a young pitch invader got the chance to sit with Ronaldo on the bench before he was led away.

After leaving China, Maurizio Sarri's men will fly to Stockholm where they will meet Atletico Madrid in another pre-season friendly.

Ronaldo, 34, is preparing for his second season with the Serie A giants, having helped them to an eighth successive Scudetto last term.

Mayorga still has a federal civil case ongoing against the footballer, who has firmly denied the allegations.
