Mourinho got a red card and is now blaming the 4th referee of the match because he is from Turin and the next game will be Roma-Juventus.
And he is accusing him to give the red card because he wants to give an advantage to Juventus.
Mourinho may think he is showing passion for the team by receiving the most red cards in the Italian league this season, but he is sending the wrong message to his players and it also affects the team when he is not on the touchline, how can you get the most red cards in the league when you are not even playing. Mourinho is accusing the 4th official of saying something he did not like to him, but he should have handled it in a calm way and later make a complaint formally. He would miss the game against Juventus and his presence on the touchline would be missed by his team, that is why he should control his emotions better.
