Brazilian attacker Neymar stormed out of Barcelona training after a bust-up with teammate n the wake of speculations surrounding interest from PSG.
In a video that has gone viral shows new signing Nelson Semedo challenging Neymar during a training session before the Brazil forward reacts angrily and is held back by Sergio Busquets.
Javier Mascherano quickly intervenes and Semedo runs back to the game, but Neymar is clearly still unhappy, calling and gesturing after the defender, and having to be restrained by Sergio Busquets.
Angril Neymar then removed his training bib threw it to the ground and fired a ball off the crossbar and booted another one before he stormed off.
Neymar has been linked with a world-record move to Paris Saint Germain, and his walkout now looks to make that move even more likely.
The session took place in Miami, with Barca in the USA as part of their prestigious pre-season tour of friendlies.
Meanwhile, Barca president Josep Maria Bartomeu has already given the green light to Neymar's move by saying the club are powerless to stop players leaving.
Neymar - who was recently cleared of tax evasion - has long been targeted by the Qatari-backed club and the star's dad has even hinted at a move.
Reports yesterday claimed PSG had started making moves to have the player's name on the back of their shirts and that a Qatar Football Association official had confirmed the move was a done deal.
