Thiago Motta insists there is no bad blood between Unai Emery and Marco Verratti, after the midfielder reacted angrily to being substituted against Marseille.
The Italy international was seen venting his anger at his mentor after being replaced by Blaise Matuidi in the 59th minute of the tie.
However, Motta has revealed that there was no lasting fallout from the incident.
"There's no problem, egos are normal in football," he told beIN Sports.
"It happens at all the big clubs, Bayern, Barca, everywhere. We're lucky to have a good group, and the Coach was completely right to speak about our frustration when we don't win.
"When I get subbed, I'm not happy. It's the same when I don't play. It's just normal, this won't be the first or last time this happens.
"Marco's reaction is nothing against Emery or anyone else, I'm sure it was just frustration about not winning the game.
"It's a reaction which just happened and it's nothing against the Coach, it was a reaction in the heat of the moment, borne of frustration.
"When you get subbed and we're not winning you can't be happy, so you can't attach any importance to something like this," he concluded.
PSG currently find themselves in third place in the Ligue 1 standings, having collected 20 points from 10 matches.
