Manchester United boss Sir Alex Ferguson is happy to be working for the club's American owners.

Ferguson praised the Glazer family, who own the club, for the constant support despite much criticism.

"They've been great owners," he said. "They have supported me every way I've asked them.

"There's no other reason to think they haven't supported me. If you look at any time I've wanted a player they've provided the money; if you look at what we've done this season - and people don't recognise this - we've spent over £20million on young players.

"We've bought Chris Smalling, Mame Diouf and Javier Hernandez.

"People don't realise how we're structured and how we see our future of the club. We've always based it on a nucleus and foundation of young players developing in the club."
