Such a subjective argument to say one is better or stronger than the other. How can you measure it?
I mean most would say prem is stronger than Bundesliga but their best frequently beat and outplay our best.
I think the only measure would be pitting all against each other. Ie take positions 1-20 from top 5/6 leagues (England, Spain, Germany, Italy, France, Portugal) and put each position in a group against each other.
E.g. Leicester, Barca, Bayern, Juve, PSG, Sporting. Group 1.
It'd never happen but I'm sure we could have some fun debating that out
Edit: maybe a bit of fun for the summer?
