Every match is carefully prepared by both coaches, so I doubt every game can be played like this. This isn't just for Inter, but for all teams. Because based on your thinking, if Udinese plays like this against all the other teams, they can easily win the Scudetto. In reality, in this case, it's pure luck. The referee awarded them a dubious penalty and also disallowed a goal for Inter, and there was also a penalty that was denied for Udinese. It's early in the tournament, and Inter had little time to rest over the summer, but it's always the same when you change coaches. After such a long time, the players have to get used to the new coach's vision, and that's not easy at all.
Unfortunately, we knew that Inter would be, so to speak, unstable, a new coach is no joke.
Your luck is that Napoli is also in deep trouble without their promising striker. So if you put your mind to it, you can make up for the prank they played last year.
However, it seems that Inter are not so unstoppable, they lost against Udinese, I am always amazed by Atta's performances, he always plays excellent football and I like him more and more, however, it is an Inter that was not able to react to the blow they took and in fact lost, this year I don't know if they will be the favourites to win the Scudetto.
