Roma coach Eusebio Di Francesco was delighted with victory over Lazio.
Diego Perotti's penalty and a Radja Nainggolan strike paved the way for the 2-1 result, although Ciro Immobile's spot-kick made it a tense finale.
“It's very satisfying for us the way we approached the game, as until the Lazio penalty, I saw real domination from Roma," Di Francesco told Mediaset Premium.
“To play a certain way, you need good physical condition, otherwise you can't press and be ready for their rapid counter-attacks. We stepped up the pace in the opening 20 minutes of the second half, pinned Lazio back into their own half and fully deserved the victory.
“I was impressed with the way we stepped up the pressure, as to be aggressive you need to run risks, and it was a risk against a Lazio side that excels in diagonal balls and counter-attacks. I think in the first half, we didn't make enough vertical passes.
“I prefer our moves to be more incisive and effective in attack. We occupy the penalty area, but Edin Dzeko is stronger at that role than the rest and we all need to work on it."
