Watch the incident below:
The 27-year-old was making his first start since January 23, but was unable to prevent a 6-5 loss on penalties after a thrilling 2-2 draw. He then slammed the club’s youngsters in the wake of the defeat, saying "they lack more ear than mouth".
"We need to be more like men in the dressing room, we must be more united," Neymar told reporters.

"They must listen more than they talk. Sometimes a more experienced guy speaks, and they answer back. The coach himself speaks, and they retort. This is not how a team goes far.
"We are more experienced, so they must respect us a bit more, listen a bit more. I had to do the same when I was starting out."
