I don't agree at all, Inter Milan had bad a performance at the start of the last season and they were unable and that's why we saw a huge gap between Inter Milan and Napoli this season and Inter Milan couldn't race with Napoli while time after time in the last weeks of the season Inter Milan had better performance and they even played in the final match of the champions league and there is the same story for Roma, however, Roma was a bit unlucky otherwise they could win the title and beat Sevilla.
It's true that Inter were very far behind at that time with Napoli and moreover Inter had lost a lot to weak teams that they should have been able to beat easily. But indeed, no one suspected something like this, even at that time I often lost money when betting on Inter's win. It looks like next season this will still happen for Inter and it is very likely that Napoli won't be the same as last season considering there are many things they have to fix with their new coach. I'm actually quite curious about what Juventus will display next season and maybe they can start little by little to try to reach the top place that has long been lost.
