Fiorentina coach Delio Rossi punched his own player Adem Ljajic during Wednesday's Serie A clash against Novara after taking exception to the midfielder's sarcasm.
With his side losing 2-0 at home to the team second bottom in the league after just half an hour, Rossi decided to act and hauled off Serbian Ljajic to bring on Ruben Olivera.
As he went back to sit in the dug-out, Ljajic sarcastically applauded his coach's decision.
Rossi took exception to the player's reaction and leapt into the dug-out and seemed to punch Ljajic in the face.
The scene continued for several seconds with Rossi seemingly trying to attack his player as Fiorentina officials tried to separate the pair.
