Jose Mourinho was involved in a touchline altercation with the Chelsea boss Antonio Conte which enraged the home fans and they abused the Portuguese, who is arguably the greatest manager in Chelsea's history.
After their loss at Stamford Bridge, Mourinho addressed the media and spoke about Chelsea fans booing him.
He said: "They can call what they want. I am a professional. I defend my club and until the moment they have a manager that wins four Premier Leagues for them, I am the number one.
"When they have someone who wins four titles, I become number two. But until this moment, Judas is number one."
Jose Mourinho was the man behind the rise of Chelsea football club in the early 2000s. After Russian businessman Roman Abramovic took over the club, Jose Mourinho was appointed as the club's manager.
Under the Portuguese, Chelsea got their recognition and they rose up the ranks to be one of the best football clubs in England as well as in Europe.
On his spat with Conte, and how he controlled himself, Mourinho said: "I managed to control my emotions and reactions - and that's good because this way I can be on the bench the next match. My players, they need me.
"It's better for me to be close to them so I think it was good for me to control it. I'm in the game and I communicated with my players and the fourth official. Nothing more than that.
"I'm really proud of my players. After Thursday in Rostov, with Rostov again on Thursday, I'm proud of the guys. Mr. Oliver goes home and can do his own analysis because I don't want to analyse his work."
