Rio Ferdinand doesn't get himself on the scoresheet very often, so there was no doubt his last-minute winner against Liverpool would be pretty high up his list of memorable Manchester United moments.
The United centre-back proved to be the match-winner against United's biggest rivals in a closely-fought battle at Old Trafford on a cold Sunday evening in January 2006.
Ferdinand rose highest in the last minute of the game to power a header past Jose Reina in front of the Stretford End, sealing three points for the Red Devils.
As he said himself: "Game done."
The win moved Sir Alex Ferguson's side four points clear of Liverpool - who at that stage in the season were United's main title rivals.
To score a last-minute winner is pretty special, but to nab one against your biggest rivals in a match with potential title repercussions - that's a truly memorable moment.
It had been a scrappy game, with both sides carving out good chances - Djbril Cisse missed an open goal in the second half for Liverpool while Wayne Rooney zipped a laser-like effort past Reina's post.
Many in the crowd were preparing to leave though - England boss Sven Goran Eriksson had already gone - when Ryan Giggs's whipped free-kick was met by Ferdinand in the 90th minute.
Cue the crazy celebrations - Gary Neville famously ran the length of the pitch - as the whole ground erupted with joy and relief.
Not known for his goalscoring prowess, Ferdinand hadn't found the net for United since his move from Leeds United in the summer of 2002.
But the 2005-06 campaign was the most prolific Premier League season of his career to date - he managed three over the course of the league term.
This header against Liverpool was undoubtedly one of his most famous, and clearly one of the most memorable for Ferdinand himself.
