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.
that's how it is. but considering qatar is a rich country. although this country is in a hot geographical location and surrounded by desert. but about money they are very prosperous. so surely the qatar government will exert every effort they can to make this 2022 fifa world cup run smoothly and a great success. because as far as I know that the middle eastern nation is a nation that upholds dignity and self-esteem. So likewise, Qatar certainly doesn't want to disappoint anyone because it concerns the country's pride. so I think this world cup will be really amazing. because the funds issued by the government of qatar will definitely be fantastic. just waiting for the time to come. we all can't wait.
Even if it is hot, it is going to be the same for everybody. So I think all the players should accept that fact and play as well as they can. The weather is going to be the same for everyone. So there is no point in complaining. The only thing that can be done is to play as well as possible.
I also agree that the Qatar government is determined to try to do everything to make sure that the environment is better for the players. Because the heat is too much we might see one or two players actually faint on the field. And that is something no hosting nation wants to see when they are hosting a big tournament like the World Cup.
