I agree, they definitively need a big victory. Last Championships were disappointing for them. But on the other hand they lost with champions - last year it was Italy, in 2018 it was France.
Fact: did you know that because in Belgium you have 2 national languages (French and Dutch, in small part of country there is also German), not to prefer one over other, players communicate in English?
https://www.bbc.com/news/world-europe-44624066I am from Belgium and I don't think they will win any time soon a big trophee (Euro cup or world cup); they always seem to fall short against the big countries. They have a couple of the best players in the world (De Bruyne, Hazard, Courtouis, Lukaku, ...) but talent is not enough. With this generation, the upcoming world cup is one of the last chances to win it.
