Neymar stormed out of a Barcelona training session in Miami on Friday after nearly coming to blows with new signing Nelson Semedo.
Footage of the incident emerged on social media, as Neymar is seen running angrily towards Semedo before a brief physical confrontation ensues.
The pair are quickly separated by Sergio Busquets, who steps in as peacemaker.
Afterwards, Neymar can be seen storming off the ground, angrily kicking two balls in frustration along the way:

The incident comes as rumours about his future at Barcelona continue to swirl.
Reports suggest the Brazilian is “90% certain” to leave the club, as he is tired of having to “play second fiddle” to Lionel Messi.
“Only a miracle will keep him, he really has made up his mind to leave,” a source in Spain close to Neymar said earlier this week.
“At the age of 25, he thinks it’s his time to win the Ballon d’Or. He believes he can be the best player in the world at another big club.”
Neymar is currently in the United States with the rest of his Barca team-mates but will not travel with them to China after their match against Real Madrid on Saturday.
He was originally set to join them, but Chinese travel agency Ctrip said his trip had been cancelled as he is “busy with transfer business”.
