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.
Inter's current points are 30 while Napoli's points are 41 so the difference in points between the two reaches 11 points. with this huge difference, I see it will be difficult for Napoli to catch up. Napoli will not waste a golden opportunity to win the Scudetto this season, they have been fasting for a title for several years, this season must be their best achievement.
