I'm down on the BL lately, completely one sided title races and this season especially their performances in Europe have been a disaster. While you can argue that the teams in Europe this season are "non-traditional" ones...they have still lost to teams like Domzale, Crvena Zvezda, Ludogorets, Braga, Ostersunds, Zorya while Dortmund couldn't beat APOEL in two games. My one big issue with Serie A is they made a mistake expanding to 20 clubs some 10-15 years back, they need to go back to 18. Too many seasons they have 1-2 clubs totally cut adrift
For 6th its between Russia/Portugal, can't comment too much as I don't watch these leagues. Portugal is very top heavy with only Braga doing anything in Europe outside the "big three" and their lower table clubs are all small and have little budgets, basically wouldn't be out of place in your standard EE league. Russia seems to have a more competitive top half (CSKA, Zenit, Loko, Spartak and throw in Rubin, Krasnodar, Rostov in the last few years having decent results in Europe). Turkey is a league which probably should be doing much better, they have some financial resources (the top clubs) but lack long term vision like a Porto/Benfica type. Galatasaray for me is the best example of this, in the early 2010s they were strong in Europe, good squad, kept Terim for multiple seasons and could have broken through as a strong club outside the traditional top 5 leagues, but then they went back to the typical Turk formula of sacking Terim for stupid reasons and then hiring the likes of Mancini, Prandelli which was impressive on paper but they accomplished nothing.
