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