Man City defender Richards: We won't let Man Utd's Rooney do THAT again
The Goal of the Season ended City's title hopes and Richards just wanted to go home, lick his wounds and feel sorry for himself.
But, not surprisingly, it was shown over and over again on Sky Sports.
In fact, they liked it so much, they even based an advert on it.
Eight months on and Richards admitted: "Of course I still remember it - how can I forget it?
"I get reminded of it nearly every single day when I see the advert for Sky+.
"Vinny Kompany just slips at the wrong moment and I came across to try to do the header - but it didn't reach me.
"It was an outstanding finish, an amazing goal. Every time I see it I wonder if I could have done something differently - I could have thrown myself full length at the ball I suppose.
"But as I always say, it was actually Vinny's man - I was meant to be taking the back post so I don't beat myself up about it.
"He was the one who got the stick after the game anyway!
"It was hard to take that we'd lost such a massive match but you can't deny it was a terrific goal."
Richards is keen to make sure tomorrow's Manchester derby will not be quite so memorable for the United striker.
He added: "Wayne still likes to remind me about it - he still feels full of confidence. But so do we.
"He won't be doing it again though, we'll be trying to keep him quiet this time.
"I think Nigel de Jong will be looking to man-mark him."
