Failure to adhere to the honorable principles of the game can lead to fights. That's what fans watching a match between the "Palmeiras" and "Flamengo" clubs in the Brazilian championship could witness.

In one episode, "Flamengo" defender Wellington collided with an opponent and suffered a blow. The referee did not notice the foul, but understanding that the footballer might have been injured, he stopped the game.

After the medics provided him with assistance, the referee awarded a free-kick and restarted the game. However, Kleber had no intention of returning the ball to the opponents and tried to orchestrate a "smart" attack, which ended with an unsuccessful shot.

This was followed by stumbles and disputes, but they managed to avoid a brawl.
