Mancini said: "Lazio started brightly and covered all the spaces, while we had a bit of a sluggish opening. After 10 minutes we started to play, opened the scoring and from then on Inter did very well."
They maintain their three-point lead over Roma at the top of the table, as the Giallorossi also won tonight, beating Cagliari 2-0.
"For now the only difference between us is our 4-1 victory at the Olimpico. Roma are doing very well and the table is already giving its verdict - Inter and Roma are the best, but in the long run Juventus could recover."
