That's quite likely. La Liga, the Premier League, der Bundesliga and Serie A are the richest leagues because of sponsorships and fanbases. There are some exceptional cases where clubs are very rich outside of this monopoly, but in general, if you were to compare the wage bill and sponsorship deals of the top four clubs in the Premier League with those of the Liga Sagres, and you'd see my point. What I'm getting at is that's why players are always attracted to Spain, England, Germany and Italy to play their club football - names like Barcelona, Real Madrid, Manchester United, Chelsea, Bayern Munchen, Internazionale and Milan appeal to moreorless every football player in the world. In England, the typical average wage is probably double that of the Liga Sagres.
