I think Napoli will be the champion, somehow my gut feeling says that seeing Napoli's efforts since the beginning of this season and Antonio Conte always has a way to provide a precise strategy, especially in the last match Napoli will play at home of course this moment is very valuable for them and want to give a gift in front of their supporters while for Inter Milan this club will play away against Como besides that their focus will be divided in preparing for the UCL final later.
I think so, looking the opponent teams for one match left between Napoli have easily opponent team by Cagliari than Inter will face Como on the top trend performance recently. Como FC have eight unbeaten matches in a row and perfectly performance under Cesc Fabregas become the only on of promotion teams in this season break to the higher standings position. Inter keep focus for winning the upcoming match against Como indeed one week later will play in UEFA Champion League final, I think have 7 days left for taking rest enough time for Simione Inzhagi keep get three points and wish Cagliari can hold draw or defeat Napoli.
Napoli have better scenario position for winning Scudetto in this season by winning the match against Cagliari, difference with Inter Milan must win the last match if won't loss chance for winning domestic league due one point remaining awhile and loss head to head make Inter Milan have secure three points, if Inter hold draw by Cagliari will fail for become the winner indeed Napoli loss from Cagliari.
