The shake of the head that Manchester United manager David Moyes has been dreading.

Here is United great Sir Bobby Charlton showing his disapproval to the painful 2-1 League Cup semi-final first leg defeat at Sunderland on Tuesday night to Moyes' predecessor, Sir Alex Ferguson, who has been a looming presence at United matches after his retirement, watching on with the same intensity that he had during his 27 year career in charge of the club.

Moyes has been at pains to point out that having Ferguson in attendance is not a hindrance, but after a third successive defeat, one can only wonder what the former manager said to Charlton up in the stands after the miserable evening at the Stadium of Light.
