La Liga - Barcelona, Real Madrid, Valencia, Villareal
Bundesliga - Dortmund, Leverkusen, Bayern, Hannover 86
Serie A - AC Milan, Inter, Napoli, Udinese
Ligue 1 - Lille, Marsielle, Lyon, PSG
Personally, I think overall, BPL's top 4 is the strongest, but I think the top 2 in the La Liga would both dominate all of the top 4 in the BPL, Bundesliga, Serie A, and Ligue 1.
I also think that overall, La Liga has the second strongest top 4, then Serie A, Bundesliga, then going onto Ligue 1.
