Thomas Tuchel was seen having stern words with RB Leipzig's fitness coach Daniel Behlau after PSG's semi-final win.
The Parisians booked their place in the Champions League Final with a comprehensive 3-0 win over the Germans.
But Tuchel, who is still on crutches after suffering a freak injury in training, was clearly upset by something.
Rather than celebrate his team's success the coach made his feelings known as he confronted the Leipzig staff member.
Thilo Kehrer and Eric Maxim Choupo-Moting watched on as Tuchel ranted.
The PSG boss will have no doubt been thrilled to see his side finally justify their owner's millions by reaching the showpiece final.
Marquinhos, Angel Di Maria and Juan Bernat got on the scoresheet for the Ligue 1 champions who are eyeing a quadruple.
Neymar and Kylian Mbappe both played starring roles and Tuchel was pleased to see his leading lights perform on the big stage.
"It's incredible! We are here to play a final and to win," he told RMC Sport .

"The team did very well. The team showed its qualities, hunger and determination. It was a good mix. And we deserved to win.
"I was very nervous, yes, and I felt the pressure.
"I have players who are used to this pressure and they love it. In football, we are never sure. But, we defended well. And it was very important. We had the right state of mind.
"Our plan was to keep our principles of the game, control the spaces and use the speed of Di Maria, Mbappe and Neymar. It's a competition for big players.
"We have to put them in comfort. We must not adapt too much to the opponent, we must show our strength. And the team showed its hunger, and its wish to suffer together."
