The Paris Saint-Germain strike duo have been in the headlines since the weekend win over Lyon, during which they persistently argued over set piece duties.
And now, former Manchester United striker Diego Forlan has waded into the debate by claiming that Neymar wouldn’t have unleashed his ego on Lionel Messi in the same way.
Reports claim that Cavani was so desperate to take the penalty as he is due a £880,000 bonus payment should he finish as PSG’s top goalscorer.
"[Cavani] deserves respect," Forlan told Radio Sport 890.
"He has been scoring goals for years and taking penalties, there has to be respect.
"Neymar would not have done that to Messi. He did not want Cavani to take the penalty.
“He was like a little boy annoying him. It's a problem between Neymar and Cavani, those things happen on all teams.
“What does not make sense is what Alves does, he doesn't give the ball to Cavani but gives it to Neymar as if he were his b***h.”
Neymar and Cavani clash TWICE during PSG match
In fact, over the course of Neymar's stay in Barcelona, Messi handed over 11 spot-kicks to his MSN colleague.
After unfollowing Cavani on Instagram, Neymar reportedly made it known that he wants the Uruguayan striker to be sold.
Neymar apparently told the French club's chairman Nasser Al-Khelaifi that it is now “impossible” for the pair to play alongside one another.
