Ferguson, speaking on The Football Show on Sirius XM, was asked how he managed to keep players happy while maintaining his rotation policy – he has not named the same side in successive matches since the final week of the 2008-09 season. At City, there have been several outbursts through the media from fringe players, the latest Micah Richards's saying last week he was contemplating leaving.
"Several things come into it, but first of all the players have to understand that, at Manchester United, we have to use our squad," Ferguson said. "I'll always explain to a player I have left out exactly what I am trying to do and the reason for not including him in a particular game.
"In general, in terms of a pay off, I have to respect the player and give him head. If he has his own opinion, great, I am happy to talk it through with him and they always know they may be playing next week and somebody else will have to sit it out.
"If we win things, then it shows the way we have gone about things is correct. If we are winning the Premier League, European Cup or FA Cup, then we know we have done the right thing."
