The ex-United midfielder recalls scoring a hat-trick on the day his replacement arrived...
There was a big crowd at Old Trafford that day and the roar when I scored just gave me a fantastic feeling. The Stretford End and the old Scoreboard End made an incredible noise.
My second goal, United's third, was from a free-kick. Ray Wilkins was stood over the ball but I fancied it, and he said I should take it based on my performance so far that afternoon. I curled it over the wall and it flew into the top corner, right in front of the Stretford End.
I was on the verge of scoring a hat-trick, something I'd never done before. It came when Gary Birtles laid the ball off to me about 25 yards out and I ran at the big centre half, weaved inside and let fly.
Winning 5-0 was fantastic and my hat-trick was the icing on the cake. I was given the match ball and Robbo signed it: 'To Sammy, from the most expensive sub in the game!'
