Snip.
Nothing is impossible, but as you mentioned, Roma are far below Inter and Napoli. For now, Juventus, Napoli, Cremonese, and Roma each have 6 points, while Inter lost. As for Roma, they look quite solid to me they’re winning matches by narrow margins, but everything seems calm and controlled. They have a good team and also a quality coach who can achieve a lot, but as you said, the focus should shift to the UCL and fighting for that part of the table.
Roma has gotten off to a good start, though they are getting a narrow win but it's still good for them as long as they are raking in the points and I hope they would maintain the pace and continue winning and probably secure a place for themselves in the UCL, that's all I expect from them, if they could achieve that then it would been a great season for them, but I do not see them winning the title, at least not for now until they are able to build a strong team that is strong enough to contend for the title.
There are quite a few good players there, with Dybala who has experience and can make a visible difference on the pitch. El Shaarawy is injured, i don’t know for how long, but having a player like that matters. The UCL sounds realistic for them, and i think they will achieve it. For now, i give the advantage for the Serie A title again to Napoli, an excellent team that already has the experience to win it.
