Bayern Munich manager Pep Guardiola says that Manchester United's failure to qualify for Europe is a lesson for all.
The Daily Star reported him as saying that it was a good lesson for the big clubs.
He said that they might think that they are unbeatable and strong, but they are not here.
He said that maybe the next season they would be out, adding that's why football is magnificent.
Guardiola further went on to take a dig at United over their failure to lure any of Bayern's star footballers to their club, saying they didn't have enough money to rope them in.
