I don't think Inter played much differently from the first 5 games, they simply played a decent team and didn't have all the luck they had in the first games.
Kongdo is very average, Melo showed is worth (rubbish) and Medel was in a panic all over the place, Guarin back to his (low) standards.
I save Icardi, who with Jovetic is the only good player. The rest is very meh, starting from the coach.
If we had someone who could be bothered to score goals, we would sail through to our 5th scudetto, very even Serie A this season.
