Modest but very important win by Lazio. Winning against Napoli is not easy, as currently they have the best defence in the league (together with Juventus and Fiorentina, who also have only 10 goals conceded). Lazio is now in the 5th place but only 3 points behind the new leader, Atalanta. Things are pretty tight at the top.
But let's not forget Inter and Fiorentina have an outstanding match to play against each other. I understand the date is still to be confirmed, but if any of them would get an extra 3 points, they would take the lead.
