Prague - European football's governing body says the Spanish league should stop challenging the decision to move the dates of the World Cup in 2022 to November-December.
A Spanish appeal against FIFA's scheduling decision was filed with the Court of Arbitration for Sport.
To avoid Qatar's fierce summer heat, the 2022 World Cup is being moved from its traditional June-July slot, resulting in European competitions stopping for around two months.
UEFA General Secretary Gianni Infantino says the Spanish should accept the decision because it was approved by bodies representing European leagues and clubs.
Speaking after a UEFA meeting in Prague, Infantino says, "It's a bit sad that people don't accept decisions taken by a vast majority. You cannot take all decisions unanimously because otherwise you would not take any decisions anywhere."
