Stop with Real Madrid and Barcelona bullshit, it may be a dream for most South Americans due to cultural, but European, Asian, and African? Do you reckon the likes of Germans, Switzerland, Polish, Czech, Serbian, Scandinavian, Nordican, and Russia would be dying to join Real and Barca because of their names and prestige, think they'd be playing for free? They offered more money, one of the richest clubs in the world and have chances of winning trophies.
Better logic, imagine if Serie A team with likes of Milan being the one of rich in Europe, they'd be more attractive for Brazilian and Argentina than the likes of Barcelona and Real Madrid because of how popular is Serie A compared to La Liga in their countries, their appeal to South American is bigger and greater than Real/Barca because of the history of how they were popular and had a lot of great South American playing for them and are very powerful financially in the 90s and 2000s. But the truth is Serie A like Milan can't compete with Real and Barca for financial anymore, not even many clubs can compete with Real and Barca for financial due to their monopoly on the TV market, even with.
PSG, City and us can compete with Real and Barca for financial but City and PSG don't feel so prestige as Real Madrid and Barca do. The only exception is that United have prestige status and one of the top 3 club brand in the world but we are not best and have been average for 5 years, If we get back to best and play better brand of football, Real Madrid and Barca wouldn't be attractive than us in most of Europe, Asia, North Americans, and Africa.
We need to get back at best or people would be thinking of moving to team where they could have chances of winning trophies but not because of their names.
