Yes, indeed Roma will face a quite difficult match against Napoli later, Napoli which is in a positive trend of course does not want to stop the current unbeaten record but I think Napoli also deserves to beware of Mourinho squad because after all Mourinho often has surprises to make his opponent lose, to currently Napoli are at the top of the standings but it's still too soon for us to make Napoli as favorites to scudetto winner this season,
In my humble opinion Napoli are favorites for the Scudetto this season, it is not because they are on top of the Italian seria a table, but because of how they are playing in the league this season, and also in the champions league, they are very strong and hard to defeat, in other seasons they may have started well and ended bad, but i don't feel the same thing will happen to them this season, i want them to win it so we would then have had 3 different winners of the Scudetto in the last three seasons.
Roma are also playing well this season, Mourinho is doing a good job with his team, they are fourth on the table and they will want to end Napoli's unbeaten run, but i don't feel it will happen, Napoli will be too strong for Roma and will defeat them.
