Belgium is a very good and experienced team, and I agree that they are favorites for one of the top two places in the group.
However, it will be very difficult for them to win the first place in the group against Croatia, who are currently playing very well and recently beat away France and Denmark in the Nations League.
At the last World Cup, Belgium was third in the world and Croatia was second, but while Croatia rejuvenated the team, older players are playing for Belgium, whose peak was at the 2018 World Cup in Russia.
I give Croatia a better chance of success at this world championship than Belgium.
No doubt Belgium was excellent team in last world cup but now in this coming event I am feeling they have no fair chance for having place into last four because even FIFA ranking giving them good advantage, but these rankings never go 100% correct here I can give Croatia better chance instead of Belgium which is surely a better team and can go through into last four.
For big events we have to be good combinations and mentality as well which is surely not going good for the Belgium, and they could be gone through until last eight which is fairly a good chance for them even in Europe we have many good teams but still most chances we will have teams like Spain, Germany and France and Croatia which are capable of having good results and can go through until last four with others are still missing something which is needed for the win.
