Bayern Munich boss Pep Guardiola says that Manchester United do not have "enough money" to tempt his side to consider the sale of their players.
Red Devils boss Louis van Gaal had several Bayern Munich players including Thomas Mueller, Bastian Schweinsteiger and Arjen Robben in his radar this summer.
However, the Dutchman was forced to look at other options after the Bundesliga champions refused to part with their players.
And Guardiola says that United will not be able to afford his players even though they spent in excess of £150 million in the transfer market this summer.
"They [United] don't have enough money," Guardiola told ESPN. "I saw they spent a lot of money. That's good for my friend Louis. I know all the players the clubs want, but it just depends on the player. If the player wants to stay, they stay."
"Manchester United wanted these kind of players, but they want to stay and we are happy to be here."
Manchester United are not participating in the Champions League for the first time in 19 years after finishing seventh in the Premier League under David Moyes last season.
And Guardiola feels that this is a very good wake up call for all the top European clubs, who take the Champions League qualification for granted.
"It's a good lesson for the big clubs," Guardiola added. "They think 'we are unbeatable and strong' and they are not here. Maybe the next season they are out."
"That's why football is magnificent. Every single week you have to be ready. Every week you have got to show you are ready. A bad 45 minutes and you're out."
Meanwhile, despite facing a lot of criticism following Bayern's humiliating 0-4 home defeat at the hands Real Madrid in the semi-finals of the European competition last season, the former Barcelona boss stubbornly insists that he will be continuing on with the same philosophy when his side open their 2014/15 Champions League campaign with a home game against Manchester City on Wednesday.
"It doesn't change [my philosophy], Nothing has changed, in the same way when you win big, big titles still have to look forward," he added.
"When we played in Madrid, we played really good with our style. But at home, we played badly, didn't control Cristiano Ronaldo, [Karim] Benzema, [Ángel] di María and [Gareth] Bale on the counter-attack. That's their style. That was their style, that is how they are strong, but we got to the semi-final and Bayern is always there in the last four."
