Patrick Vieira and teenager Balotelli struck Inter's goals and coach Roberto Mancini beamed: "Are we worried by Roma? In all honesty, no. Success in this campaign is only up to us. In the last two seasons our fans have been spoilt by record-breaking victories, but results like last term happen once every 50 years.
"It was a good game in a tough arena against a team that is going through an excellent period of form.
"Our midfielders are starting to get their fitness levels back and you can see the results. We allowed our opponents very little and covered the defence well. Patrick Vieira also scored a very important goal."
He added: "Mario has great quality and is very young, so this allows him to take on this type of game with the typical joyous approach of someone his age."
