Last time the African teams struggled to adjust to the difficult weather conditions in Russia. This time that should not be a problem. And among the less fancied UEFA teams, Serbia has the momentum right now. My concern is that they have always underperformed during the world cup. Anyway, this time they are placed in a very tough group along with Brazil and Switzerland. If they are able to manage a draw against these two teams, then they can qualify to the next stage if they defeat Cameroon by a large margin.
Hot weather will help African countries on 2022 FIFA World Cup in Qatar and give difficult with European countries because they have adapt with Asian region really hot and their country have cold weather. I think will be credit points actually for Asian and African countries participants on 2022 FIFA World Cup in Qatar how they can talk until final stage. Although many predicting doubt with African participants I think have African country will make surprises result, will see they can lead until semifinal for this World Cup time edition like Senegal or Cameroon.
The World Cup is played late in the year just to curb on the heat in Qatar. It will be played in November so that the place is much much cooler than the usual time of June-July. It will be about 19-28 degrees around November which is quite pleasant for most countries.
