It's a shame AC Milan had to meet Napoli in this round. My previous hope was that Milan would meet a team outside of Italy to be more competitive. However, there are other things that make me doubt even though Italy managed to bring 3 clubs to the quarterfinals, because 2 of them are very inconsistent teams in Serie-A..
You are right. although of course the Italian League should feel proud because the number of teams that have qualified for the quarter-finals from Serie A is quite a lot, namely 3 teams. But the consistency between Inter Milan and AC Milan is indeed questionable. although there is still enough time for them to practice until the quarter-finals are held. but I don't think there will be much change. and only Napoli actually looked very convincing to qualify for the Semi-finals. Inter and Milan are really faced with teams that have a good level of consistency this season. as Benfica and Napoli have both been outstanding in their respective local leagues this season.
