Yes Juventus dont do well against english teams,and yes for the last 2-3 seasons english teams have had quite a few teams in the semis.But well,last year there were 3 english sides in the last 4,and only 1 italian side.Try guessing who won the CL.
I wont say that the Serie A was stronger than the EPL last season,but if you're going by facts,then they can support you as easily as they can go against you.It just depends on how you twist them.Stadium attendances in the Serie A are in decline,there is no question about that,but here's another fact : Since 2000,5 different teams have won the the Serie A.During the same period,only 3 different teams have won the EPL.Does that imply that the Serie A is more competitive than the EPL?maybe.maybe not.Since 2000,3 players from the Serie A have won the golden boot.No one from the EPL has won it during this team.Does this make the quality of players in Serie A better than those in the EPL?maybe.maybe not.
I loath the EPL and almost everything that is related to english football,but even the biggest fans of the EPL cannot deny that a massive chunk of their supposedly 'biggest league' in the world status comes from their popularity and not exactly the quality of football.
