While many of Manchester United's stars are already home from Qatar, Lisandro Martinez and Raphael Varane remain at the tournament.
With France and Argentina both set to play two more games at the World Cup, it is unlikely that the two centre-backs will get much time to train or rest between the end of the World Cup and United's first game back against Burnley in the Carabao Cup.
While United can probably manage against Burnley without their starting defensive duo, they will be hoping that they'll both be fit and ready to face Wolves on December 27 when they resume their Premier League campaign.
