Well, there's at least one this year. Is immobile a top forward? Clearly not. Was Quaglierella the best forward in Serie A last year? Of course not, but he got 9 PKs when Zapata and Piatek only had 1 and 2.
Also, you can't compare Juventus in Serie A with PSG in Ligue 1, its more complicated than that. Yes, PSG is more dominant but our players have to share the scoreboard between Mbappé, Neymar, Di Maria and Icardi (18,13 (with injuries), 12 and 7 goals). At Juventus with far more game, the 2nd best scorer is dybala with 11 goals.
But i'd make a step in your direction by removing "by a long shot", it might be excessive and i don't like arguying this way.
