And actually they still have a chance to compete for the title if Napoli throw away a lot of points.
I see it's impossible for Inter to catch Napoli, and it's also impossible for Napoli to just throw away this golden opportunity for them to become a scudetto, maybe Napoli can lose or draw in later matches but Inter must continue to win without also wasting points, and also other teams who are competing for the championship must suffer a drop in form which is why I say it is quite difficult for Inter to catch up.
As said, other teams competing for the title have suffer a drop in form, including Napoli. Although in the end I still consider Napoli's feasibility to survive among several other competitors. However, with the remaining time of Serie A before the end, it can be a boost for all teams to play optimally and can also be a big threat for Napoli.
Will they give up the Champions League to shift all focus to Serie A, or vice versa? I think Napoli need to consider one of them to maintain their consistency
