Spain's squad in the recent round of qualifiers featured 21 Spaniards and two Brazilian mulattoes Thiago and Rodrigo. They're both 28 and are not guaranteed starters, and are either prone to injuries or dips to form.
Italy's squad had 21 Italians. Also included were the Brazilian Jorginho who has some Italian heritage and the half Egyptian/Italian El Sharaawy who plays in China and has a tenuous place in the squad.
Germany's squad in the recent qualifier against Estonia had 16 Germans, 2 blacks, and 3 Turks (Gnabry, Tah, Amiri, Can, Gundogan). Gnabry has made a big impact in his appearances and Gundogan has been a fixture in the side. Black winger Sane is injured until early 2020, and it's likely that Gnabry and Sane will start for Germany in Euro 2020.
I would say that Spain, Italy, and Germany are painfully average at the moment. They don't have a Ballon d'or caliber player to grab by a game by the scruff of the neck. Belotti and Immobile for Italy, Werner for Germany and Morata for Spain are decent enough players but are a million miles away from a Kane or Lewandowski. While Germany's great black hypes Gnabry and Sane don't have the ruthlessness and mental strength to be world-class.
Even Sweden, Norway, Denmark, and Finland have blacks contaminating their national teams. The Sweden vs. Norway qualifier in September featured 20 Swedes, 1 Arab and 2 blacks Robin Quaison and Alexander Isak for Sweden. Norway had 17 Norwegians, 2 Arabs Aleesami and Elabdellaoui, and 4 mixed blood blacks King, Gabrielsen, Johnsen, and Grytebust. Denmark's qualifier in September featured 19 Danes and 4 mixed blood blacks Jorgensen, Billing, Braithwaite, and Poulsen. Even Finland in its qualifiers this month featured 21 Finns, a mixed blood black Pyry Soiri and straight out of the Congo Glen Kamara. Denmark's population is about 87% Danish and an additional 5% consists of other European migrants. There are only 5,000 people from Nigeria, Ghana, and Cameroon living in Denmark, yet somehow nearly 20% of Denmark's national team is currently composed of blacks.
Against Serbia in September, Portugal had 19 Portuguese players and 4 blacks: RB Nelson Semedo and midfielders Danilo Pereira, Renato Sanches, and William Carvalho. With Andre Gomes returning from injury, he should be expected to knock out one of the midfielders from the team. Overall, Portugal may have up to 20 Portuguese players on the squad in Euro 2020. And I think that with the experience that Ronaldo, Moutinho, and Pepe bring together with exciting younger players like Bernardo Silva, Joao Felix, and Ruben Neves, Portugal should be favorites for defending their European championship and knocking out that ugly France team.
French football is literally and figuratively in a dark age right now. Not only that, but they are contaminating football clubs across Europe by exporting big, brainless players like Kurt Zouma and Tiemoue Bakayoko. I do not see a potential French superstar in his early 20s at the moment, no one to follow in the footsteps of Griezmann, Ribery, Zidane, and Platini. France don't even have a French goalkeeper at the moment to take over from the aging Hugo Lloris. The only bright spots of French soccer right now is the development of a few world-class defenders in Laporte, Lenglet, Pavard, and Lucas Hernandez. In qualifiers played this year, Deschamps has selected only 6 or 7 French players. At the same time, Deschamps appears to understand that he has to depend on at least 4 or 5 French players in his starting lineup and that he cannot solely rely on blacks. In Euro 2020, Deschamps will probably only select 7 French players: Giroud, Griezmann in attack, Lloris in goal, and Lenglet, Hernandez, Pavard, and Dubois in defense. While some other French players Laporte, Rabiot, Digne, Thauvin, Lecomte are on the fringes of the team and it's possible Deschamps will call on them.
Holland are a far cry 2006-2014 golden age led by Sneijder, Robben, van Persie, Kuyt, and Huntelaar. In the recent qualifier against Northern Ireland, Holland had 12 Dutch and 11 blacks. They do have some serious gems with midfielder Frenkie de Jong and defender Mathijs de Ligt who are already among the best players in the world at their positions. But their attack is overwhelmed by flashy, ineffective black wide players such as Depay, Bergwijn, Promes, and Malen, who together aren't good enough to shine Robben's boots. Holland interestingly have several white strikes in Luuk de Jong, Bas Dost, Wout Weghorst, but their attributes are limited to aerial prowess and poaching in the penalty box.
England has progressed considerably with results with the emergence of Harry Kane and the improvement of Sterling in the last 2 seasons, and I find that they can be contenders for Euro 2020 if those two remain in hot form. Southgate in recent qualifiers picked 12 Englishmen and 11 blacks. Unlike France, England do have some exciting emerging talents with Declan Rice, Mason Mount, Jack Grealish, James Maddison, Ben Chilwell who have been excellent so far this season. It seems that in England, there is an unwritten rule that a right-back must be black. You'd have to go all the way back to the World Cup in 2006 when England last had an Englishman start at right-back.
In the recent qualifier against Kazakhstan, Belgium featured 17 Belgians, 5 blacks, and the Arab Chadli. And there are genuine superstars from Belgium with Eden Hazard, de Bruyne, Mertens, and the world-class CB pair of Vertonghen + Alderweireld. The one strange outlier with this squad is how all of their strikers - Lukaku, Batshuayi, Benteke, and Origi are straight out of the Congo, and they only combined for 22 league goals in 2018-19.
