Is David Beckham still scared of Alex Ferguson?

He might have asked his old boss to return to the Manchester United bench to take charge of a charity match, but it seems he's still a little intimidated around the Scot.
Beckham told BBC Radio 1: “The other day I saw him for the first time in a long time. We’d never even think about having a little glass of wine or beer (as players) in front of him but the other day someone handed me a glass of wine and I was talking to him (Ferguson) for 20 minutes with the wine hidden behind my back.
