Many always consider Belgium to be a dark horse, but this country never lives up to expectations and only once were they able to finish third at the last World Cup. By the way, it's not a one player team. I take it you are talking about Romelo Lukaku or Kevin de Bruyne. Apart from those players, they have one of the best goalkeepers in the world Thibaut Courtois, midfielder Axel Witsel, strikers Dries Mertens or Eden Hazard. With players like that, they should be successful because it's likely that at the next World Cup, a lot of players will leave the national team.
Belgium have a good team that
were capable of winning an international trophy for the country, i feel if they were to win something it would have happened either in the 2014 or 2018 world cup, or the Euro tournaments that have been played between that time, because that was when their star players were at their best, since they didn't win it then, they can't win it now, most of their best players are not as good as they were around 8 years ago, like Hazard for example, kevin de bruyne is still a great player, but i think he was better around 4 years ago. Belgium still have a good team, but i feel they are incapable of winning the 2022 world cup.
