Like I've said before, I understand why the Spanish and Italians would want a Super League. They just can't keep up with the English leagues.
Losing players to the likes of Wolves must be galling considering you're FC Porto. But Wolves etc have been put in the positions that they are because English clubs have been doing things the right way, in terms of distribution of TV money at least, for decades.
I don't know about the Portuguese leagues, but the Spanish big two screwed over their fellow clubs and the whole league with their business models and TV deal. Where are the likes of Valencia, Deportivo, etc now?
Some kind of pan European league would probably come into existence in our lifetimes. It's kind of inevitable.
