Neymar enjoyed an eventful training session on Sunday as Brazil stepped up their preparations for their final World Cup group game against Serbia.  

The 26-year-old had plenty of fun during the session as he rolled around on his back and was also seen celebrating.  

In addition, Neymar had his ears flicked by his team-mates after losing a game in training.

Despite having plenty of time for playing around, Neymar also showed his serious side in training as he demonstrated his excellent close control.

The rest of the Brazil squad also appeared in good spirits as they were put through their paces by coach Tite.

If Brazil are to enjoy a successful tournament then Brazil will need to ensure that Neymar remains happy, and he certainly seemed in buoyant mood.

Going into the tournament there were concerns over whether Neymar would be fully fit after he missed the last few months of Paris Saint-Germain's season due to a fractured metatarsal.

Neymar scored a late goal in Brazil's 2-0 victory over Costa Rica in their previous group stage fixture as they bounced back from drawing 1-1 with Switzerland.

A draw against Serbia on Wednesday would be sufficient to see Brazil make it through to the last-16 stage.
