Roma president James Pallotta has continued his feud with the club's ultras.
Fans barracked Pallotta at the team hotel before the derby win over Lazio.
The ultras chanted: “Now where is James Pallotta?"
La Gazzetta dello Sport reported Pallotta's response after the derby.
“To those protesting, I'd like to say that during the derby I was the one singing, 'Now where is the curva?'
“I'm very pleased. Roma played as a team for 90'. As for the ultras, I'd like to remind them that I'm in Boston, trying to get a stadium built for Roma. Maybe they'll appreciate this?
“The team seemed in great physical shape, I just hope that [Mohamed] Salah is ok," he said, in reference to the Egyptian striker who was stretchered off the pitch.
“The foul could have been worth a red card."
