Wow, this is a very tight match. Even Lazio was able to dominate the situation during the match. Moreover, Lazio's early goal shocked Napoli a bit, but they were quick enough to equalize the score.
..............
Now we just have to wait for the results of the Juventus vs Inter Milan match. If Inter Milan wins, Inter will take over the first place in Serie A.
It is always disappointing to lose a late goal, but Conte has tried his best and Lazio has been playing very well. Fair result, neither of them deserved to lose, the draw was fair and it was based on what was seen on the pitch.
Tomorrow it is Juventus vs Inter, Napoli's fate at the top of the standings is determined by Juventus and if everything goes well, Juve will beat Inter. I will not say anything else. 
Fortunately, Inter lost to Juventus, so Napoli is still at the top of the standings, occupying the first place in Serie A, with a difference of 2 points. Well, this is always outside the prediction, I even think Inter will win, it's just that Juventus can actually optimize the moment in the home game.
Anyway, the UCL match is almost over. Unfortunately, the clubs from Serie A who participated in the preliminary round this time had to go home disappointed.
Atalanta was defeated by Club Brugge with a score of 2 - 5
Milan was defeated by Feyenoord with a score of 1 - 2
