I fail to see your point- Brazil and Pele were great and Brazil as a country must be one of the most racially mixed countries ever. Thus, the happy message could perhaps be that we should mix up the gene-pool anyway. But race does not matter in soccer for the most part.
But, from a purely physical perspective, I know from contact with people involved in an elite team in Norway who have recruited players from several western-African countries that they consider these players to be superior with regard to speed and explosive strength.

Brazil and Latin America's (and the US to an extent) racial politics show that it is not a happy message.
The lighter you are, the prettier, and you are of better status. The more negro, the opposite. In many Latin American countries, to associate with the term or word "negro" or black, is seen as a negative---it means poor, ugly, etc.
If I am correct, the saying in Brazil is "A white woman for marriage, a mulata woman for sex, and a black woman for work", oddly in Brazil the mulata is often a brown to light brown skinned black woman. The "black woman" is dark skinned. And Pele himself has an adversion to black women.
Basically, Euros have propped themselves up as the standard bearer and people of color seek validation.
There is no Utopia of mixed race equality.
A good blog to read.
