Real Madrid legend Ronaldo has slammed Barcelona ace Neymar over his Copa America antics.

Neymar suffered a meltdown in Brazil's defeat to Colombia.

"He's behaving very aggressively and it's something that cannot be tolerated under any circumstances. These things just should not happen in a match", Ronaldo lamented, although he also accepted that such behaviour may be because the starlet is "going through a bad time" off the pitch.

"When you are wearing the Brazil shirt, you can't behave like that."
