I think Napoli are still quite superior this season in defending the Scudetto trophy because they have a squad that has hardly changed drastically in this transfer window. So their mentality is still strong enough to provide a strong competition for their challenger team.
No one doubts Napoli this season they are strong candidates for the title only injury issues could mess them up due to lack of reserve players
let's pay attention to the top scoreboard we still see the same name there as last season there is only Olivier Giroud as a newcomer
but I'm sure it's only temporary, in the near future there will be another player to replace him like Dušan Vlahović.
