Manchester United boss Sir Alex Ferguson was left stunned and embarrassed during a recent trip to a local lschool.

The Mirror says Ferguson was left with an even redder face than usual during a tour of a school in Gorton, Manchester with Foreign Secretary David Miliband last week.

First one scallywag handed embarrassed Fergie a mobile phone displaying an animation of his rival Rafa Benitez in a rather compromising position.

Then Miliband pointed out to the kids that Sir Alex was wearing socks in a fetching shade of Manchester City blue.
