actually I was incorrect, what happened was 4 leagues were given 4 places (was 3 before) - also there is this for the clubs coefficientsAnd what is considered "top leagues" is decided by the coefficient, so it does matter.
- Historical success in the competition will also be acknowledged in coefficient calculation (points for previous European titles with a weighted system for UEFA Champions League and UEFA Europa League titles)
So if you won the CL in the 90's you will be more likely to be in a higher pot.
