Manchester United assistant boss Carlos Queiroz has revealed Sir Alex Ferguson has never questioned his tactics.

"On my first day at Carrington (training grounds), Alex introduced me to the group and told me: 'Get on with it'", Queiroz told Le Monde.

"Since that moment, he has never interfered with my work. And when things are going bad, Alex never lets me down.

"The big difference with United and Real is that at Madrid the directors and the press want to control the club. And the chairmen think they know football!

"At Manchester, the only bosses of the team are coaching staff members.

"A few days ago we lost at home against our arch-rivals Manchester City. We were able to think and work in the days after, but after such a defeat it would have been impossible in Madrid."
