I mean, do you even understand what is it like playing in regional league?
If we are playing one today, we could be facing top opponents like City this week, then possibly dogshite opponents like Salford City on the other weeks. Leagues are basically organised in regional basis, which means clubs will be facing all the local teams, and could include all the dogshite too (depends on overall strength of your region).
Whereas other top teams located far away from your region (ie Liverpool, Chelsea, Arsenal), you don’t even get the chance to play against them under regional league format. So we will be only playing against a few PL teams from our region, a few from Championship, and possible a few from League One or Two too under such format.
National league system was only implemented in Brazil after 70s. Hence for majority of Pele career, he was playing in sub standard format of league system.
