I just realized that for the first time there were six teams from Asia (AFC) who managed to advance to the world cup. I think this is new history. I have high hopes for South Korea and Japan in this world cup. although the real challenge will definitely be felt for Korea and Japan because considering Qatar is a pretty hot country so I hope it won't be a problem. even some of my brothers who work in qatar say it's so hot there even at work there is someone who installs air conditioning outside the room. This will definitely be a challenge for a team from a country that has cold temperatures.
adaptation must be done as soon as possible by players from cold-weather countries. they can arrive early and try to get their bodies used to train and matches in the heat.
but usually, in official matches with the host country's weather being quite hot, there will be regulations regarding technical breaks for players to rest for a few minutes between the first and second half. it seems that way should also be done in Qatar. because the hot weather can drain the stamina of players. especially for those who play with short breaks.
