Knees shaking, lip quivering, heart pounding. The cacophony of sound pounding away, whilst one waits in the tunnel awaiting their Manchester United debut. The nerves hands begin to tremble, and the fleeting desires for the ground to swallow them whole and provide them with an escape from what could be a torturous afternoon. At least, that's what one can surmise it is like to nervously prepare for a Manchester United debut. The nation's biggest club, a plethora of media outlets focusing on your every movement - not only is it important to get off to a good start at Old Trafford, but it is vital. Such is the pressure of representing a club of such a magnitude, there have been those unfortunate footballers who have never recovered from a shaky start to their Red Devils' career - step forward messrs. Miller, Djemba-Djemba and Forlan.
