Haven't heard about Pogba in a while. How is he doing out there? If I am not wrong, Pogba was the first star player to get injured before the world cup. The schedule of the world cup is partly to blame. Because of COVID restrictions, they moved the world cup to November. And this overlaps with many of the European leagues. A lot of players get injured during these club matches, because they are fiercely fought. Anyway, everytime some of the main players miss the tournament due to injury. Qatar 2022 won't be any different.
Are you confusing anything about Qatar and Covid? Qatar won the right to host the World Cup back in 2010, and it was initially assumed that due to the climate, the championship would be held at such an exotic time. Covid has nothing to do with it.
As for Pogba, he's still recovering from injury (and surgery) and appears to be doing well, but Deschamps said it's not yet clear if he'll include him in the squad.
