Lazio president Claudio Lotito has lifted the lid on his bust-up with Roma coach Jose Mourinho.
The pair clashed outside the Olimpico dressing rooms after Lazio's derby win on Sunday.
Lotito told Radio 1: “I celebrated the derby like any other moment, matches are won and lost, but there is great satisfaction from the team and support from the fans.
“I am all for respect. I didn't utter words, I saw a scuffle between one of my players and a Roma player. One thing did not go down well with me, that there was the Roma player completely naked in the corridor.
“I stopped and Mourinho shouted at me 'what are you looking at?', I thought he hadn't understood that I was the president of Lazio and I pointed it out to him, he went on.
“I never told him he couldn't be there, only who I was. We didn't argue because I don't argue with anyone, it's a problem of roles that have to be respected.
“The match was Lazio v Roma, Roma were guests. It's as if a guest arrives at your house and behaves in a certain way."
