AMAD DIALLO was sent off just seconds after scoring Man Utd's winning goal against Liverpool.
The Ivorian slotted the ball home in stoppage time in extra time to give the Red Devils a famous 4-3 victory over their fierce rivals and send Old Trafford wild.
But emotions got the better of the winger, 21, as he removed his shirt to celebrate with the fans.
And having been booked five minutes earlier, referee John Brooks had no choice but to show him a second yellow card.

As a result of his dismissal, Diallo will serve a suspension.
However, he will NOT be banned from Man Utd's FA Cup semi-final against Coventry.
