Sir Alex Ferguson says it's crucial David Moyes' backroom team at Manchester United are fully behind him.
Moyes has taken criticism for bringing in his own people.
But Ferguson says: "Three things are very important when you are working with them - work ethic, loyalty, philosophy.
"You all have to be singing the same tune, no matter how bad the tune is. It's important that your people agree with you and the way that we at United wanted to play, that was very important.
"My attitude to a game of football - never give in. At half time in a game of football, if you're behind, never give in."
