All Blades heading to Bramall Lane on Wednesday night will be hopeful of a similar outcome as back on that cold, blustery night in December 2006.
United ran out worthy 1-0 victors against the Gunners, with Christian Nade scoring the only goal just before the break, after outmuscling Kolo Toure on the halfway line.
Then, on the hour mark, Paddy Kenny sustained a groin injury and with no substitute keeper on the bench, Phil Jagielka took over between the sticks and went onto produce an unbelievable match winning performance, which sent the Lane faithful into delirium.
A repeat performance by Bryan Robson's men in front of the Sky live cameras would be what all Unitedites are craving!
