Did anyone realize that the competition in Serie A has not been up to the mark?

By that, I mean almost all of the teams in this league have just not been good enough in the Champions League competition. The last time any Italian team was able to win the Champions League competition was back in the 2009-10 season if I recall correctly. And it was Inter who won the Champions League.

After that, I do not remember any team from the Italian league actually winning the Champions League title. Are the teams in the Serie A has just become that bad? I know recently a lot of Italian teams have been facing some legal problems with their players, their coaches, and even their owners. Are these the reasons why they have not been able to do well in the Champions League competition? That is definitely a factor if you ask me. It also does not seem like any team from the Italian league will probably win the Champions League competition anytime soon.
