All the team you have mentioned are superb team - but I am thinking of another point that is Qatar is an extreme weather country and these all teams are from the cold regions. Would that not be affecting their performance there? Once the matches start .. the situation will be clear.
I'm also a little worried about the same thing. because the temperature in qatar can reach 42 degrees celsius. and for those who are not used to it, it will be very torturous and will make stamina easy to drain. but fortunately the news said all stadiums in qatar for the 2022 fifa world cup will be equipped with air conditioning. so players can play without worrying about the heat. and the audience can also watch in the stadium without worrying about feeling hot due to the air temperature there. I hope the news is true.
Surely a big worry for Western countries if temperature is going to 42 degree Celsius then surely they are going to suffer and have side effects of this as well because Qatar is almost desert, and they are not having any better environment for these Western players those are mostly playing into cool weathers. This is going to be beneficial for South American countries as their players are well-prepared for this all, and they can't suffer like European players and this advantage can give them their first success after two decades, and they can win this year's event.
Qatar's authorities and FIFA officials are already working on few things which can used for first time because it's first world cup into the Middle East, so they want to do their best for having their desired results but still it's not easy to play and giving best results in these conditions.
