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.
The only way that they lose the scudetto is by being affected by this world cup stop and lose their momentum and start losing points even though the chance of the other teams not losing any is really slim, all milan inter and juve are beatable and i don't see any of them as champion.
