Arsenal and several Premier League clubs could struggle to field a strong team for their last Premier League match before this World Cup.
This is because the South American footballing body, CONMEBOL, wants the players of their competing nations to be released from Wednesday 9th of November.
The Sun reports this request means they want their players released earlier than expected.
The players were initially expected to leave their clubs after the league games that weekend.
But South American nations want to spend more time with their players before the competition kicks off.
FIFA will now look to broker an agreement between the clubs and the governing body.
