Bayern Munich manager Pep Guardiola said Manchester United can't afford to sign his players, according to the BBC.
United's offseason included spending more than £150 million on new players, including a British record £59.7 million to sign Angel Di Maria from Real Madrid.
Guardiola said he is confident none of his players will be leaving for a larger salary from United.
"They don't have enough money, I am sorry," said the 43-year-old Spaniard.
"I saw they (United) spent a lot of money. It is part of the game. It just basically depends on the player. When the player wants to move - they are going to move."
Bayern, the two-time Bundesliga defending champion, has started the season 2-1-0.
United has opened 1-2-1 in the Premier League under new manager Louis van Gaal following a seventh-place finish last season.
