In the past Serie A was the most attractive league because of its highly competitive rivalry, but when the case of match-fixing and or calciopoli and then it made Serie A lose confidence and also decreased audience interest. It took a long time for Serie A to recover but over time, the Premier League became the most attractive league until now. But indeed, despite this of course Serie A is still an interesting league to watch and that is proven, in the last season all representatives of Serie A clubs can reach the final in Europe. At least it is also proof that, the performance of Serie A teams is still growing from season to season.
Serie A was clearly one of the strongest leagues in Europe before their overall league competitive performance began to decrease. We had AC Milan, Inter Milan, and Juventus, among others, who were all in excellent form and consistently dominated European competition. All of these teams are still performing well, and there are more on the way who have been excelling in European competitions. I'm not sure what caused the league's general performance to fall; might it be a shortage of quality players, as it was previously? But I love the zeal currently in the league, and they're doing better than ever, as evidenced by how most Italian clubs performed in European competitions they participated in last season.
