If you look at the performance of the two teams in the last few matches, of course, Napoli's chances of winning are much greater.
Napoli is the most consistent team to date whereas it's all in contrast to Roma.
I think even though Napoli will play away it won't have a big impact on them, their front line has been very productive in the last few games, I think they will be able to score some goals in this game.
I will bet on Napoli's victory in this match, even though it takes a lot of risk but their chances of winning are much bigger.
