Neymar arrived for a world-record fee during the summer and has bagged eight goals from as many games in all competitions for his new club.
However, it has not been all plain sailing as he was seen to argue with Cavani over free-kick and penalty duties during PSG’s 2-0 Ligue 1 victory over Lyon last month.
There have been conflicting reports of a huge rift, with club stalwarts siding with the Uruguay international but officials standing in the other corner.
The issue now appears to have been resolved to a certain extent and Marquinhos feels that it could even have had a positive effect on the players.
"The conflict with Cavani is normal," he said ahead of Brazil's World Cup qualifier with Chile on Tuesday. "It's a good problem for the coach to have two players with that responsibility, who want to be a part of that moment.
"They are two great players and it's all fitting together in the best way."
