Roma goalkeeper Julio Sergio admits he was amazed by the behaviour of Lazio's fans for their defeat to Inter Milan.
Lazio fans were happy to lose to Inter as it prevented Roma from staying top of the table.
"Lazio-Inter? I have nothing to say. Inter won and that is the end of it. We must focus on playing Inter in the Coppa Italia Final tomorrow and doing well in the last two rounds of the season," said the shot-stopper.
"In Rome there is an incredibly high level of competition between clubs and the rivalry goes beyond anything I've ever seen.
"In Brazil there is rivalry between clubs when you play against each other, but not when a result can affect a different side.
"We'll have to see where all this could lead."
