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."
