Leaked UEFA documents published by L’Equipe suggest national team coaches will have just one week to prepare for the 2022 World Cup in Qatar.
According to the French newspaper, players will only be released to their national teams by clubs from November 14.
The tournament is due to kick off in Qatar on November 21 and run to the Final on December 18.
This will be the first time the World Cup has been played in the winter, a solution required after assigning the tournament to one of the hottest countries on earth.
The Champions League will also be brought forward to start from September 6, finishing the group phase in early November.
If confirmed, this will create even more controversy and anger around the decision to play the 2022 World Cup in Qatar.
There are already complaints about the change of scheduling and the poor human rights record of the host country, including deaths during the construction of the stadiums.
