If you realize that inconsistency is happening to Milan as well and not only to Inter, because at the same time when Milan and Inter have weaker opponents they can end the match with a loss as well as a draw. So basically last season their inconsistency can be said to be balanced, so I can't agree if the inconsistency is only aimed at Inter. But however the season has passed and will start a new season in a few days, the preparations of the Serie A teams I think so far only Juventus has seen a major overhaul and I am looking forward to Dybala's performance at Roma under Mourinho.
Any Serie A fan or gambler who often takes advantage of the match will be well aware of it. The inconsistency of the Serie A team last season has made Milan win the title, but of course I believe Milan also has a good performance.
About this season there are a lot of teams that are starting to improve. Several new players have been signed and this will be good for Serie A as the title race will be intense. Roma in competition, Milan, Inter, Juventus and Napoli will also make Serie A even more interesting.
Not just Serie A amost all leagues do the same thing at least in the last 2 seasons or during the corona virus period
We see this season looking better every team prepares the mainstay player to take place in the standings
