I think it's confirmed if we're having two title contenders this season. These are Napoli and Intermilan. The odds said it all. They're widening their gap to the Atalanta, which is number three.
The success of Napoli beat Juventus has proven it they're ready for the title race. It's also officially eliminated Atalanta from the title race.
As for the winner, i'd pick Intermilan. Hopefully, Napoli does shit at the end of season.
This like what i've said Atalanta would not be competing for the title. Finally, it's happening.
Atalanta made big impression in this season but maybe it's not enough for them to win Scudetto. This season anyway can be a foundation for them, to experience Scudetto competition, and can help them to compete for it better in future. If Atalanta continue their growth, it will come to time they are able to win Scudetto like Napoli did three seasons ago after many past seasons failed to get it.
In my opinion, Atalanta has not given up but their chances are still there in the fight for the Serie A title even though in the last few matches they have failed because some of their players were injured and one of them is Retegui and now he has returned and managed to bring victory for Atalanta when visiting Como's headquarters
Their situation now is not too good but surely Atalanta will not give up early. They have many players who experience Scudetto competition for a first time of their career, so it's valuable experience for them. No reason for their players to give up while opportunity still exists for them, if they continue to fight and can return to good performances.
Return of Retegui, their main goal scorer in this season, is important for their attacking power in particular and their competitiveness in general for rest of season.
