Roma have shown an improvement in their performance. but to fight with Napoli won't be so good for them. Napoli are much more consistent and of course have better confidence in facing Roma. If Roma manages to end the match with a draw, it's good IMO.
Lazio vs Atalanta, have equal strength IMO. it will be a fierce match. However, the draw with Udinese experienced by Lazio is likely to affect their match slightly.
Napoli are on a 10 win streak right now, I like the stats and that's why I can say that no streak can last forever. Roma is quite capable of taking points from Napoli, it would be interesting if Roma could win, but Napoli is now like a locomotive that has picked up speed and is very difficult to stop. In any case, I think Roma has a chance. Atalanta and Lazio are the two best defenses in Serie A at the moment, but they are also good in attack, here I am more inclined to a careful match and I think that Atalanta will not lose.
