But in terms of final standing, it’s the same.
Sure LL during 2010s is much stronger with Messi/Barca and Ronaldo/Real both in their peak. But discussion had been whether Ronaldo was failure at Juventus during his time there (past 3 years). If he is, so is Messi (past 3 years).
Reason being, since 2018, his main rival Ronaldo is gone and Real becomes considerably weaker, and later Barca also bought Atletico’s best player Griezmann and Atletico becomes considerably weaker too. With 7 titles already won in past decade and their main rival getting considerably weaker, Messi Barca should run away with LL titles, but they didn’t.
