Manchester United boss Louis van Gaal says Robin van Persie will miss their Premier League kickoff.
Van Persie has been on holiday since helping the Netherlands to finish third at the World Cup in Brazil last month and will return to training on Monday.
"Robin will begin training on Monday but he won't play against Valencia, definitely not," said van Gaal. "He won't play in the Premier League either.
"When a player has been on holiday for three weeks they have to train.
"I'm sorry but players have to train and Robin needs a full training regime behind him before he can play again.
"People can criticise me for my decision but I know what to do with players who have had three weeks' holiday.
"Hopefully, Robin will get his fitness back very fast but, for now, he won't play.
"Robin wants to play every game, I know that, but so do the other 30 players in the squad."
