Training was halted because of the incident and Neymar is then seen taking off his training bib before storming off the pitch.
Sources understands Neymar wants to leave Barcelona as he has become increasingly frustrated at "playing 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 told News sport earlier in the week.
"At the age of 25, he thinks it's his time to win the Ballon d'Or," the source added. "He believes he can be the best player in the world at another big club."
Neymar had been due to fly to China after the Real Madrid match but Chinese travel agency Ctrip said that had now been cancelled as he is "busy with transfer business".
Ctrip said the event was scheduled for Shanghai on Monday and that anyone who had bought tickets would be refunded.
