Apart from the obvious one's in the OP:
Nasri's goal in the league cup final. The most similar to the Aguerooooooo moment celebration-wise. Was mental.
Dzeko's winner at West Brom.
Nasri's goal against Chelsea in 2012.
Tevez's goal at the swamp in the league cup semi.
Kompany header vs Rags 2012.
Adebayor header vs Arsenal.
Aguero's goal vs Rags last season.
Barry header vs Reading last season, 90th minute winner.
Richards header vs Villa 2006.
Balotelli 90th minute penalty vs Spurs 2012.
Micheal Johnson vs Derby 2007. Weird one I know but for me it felt incredible since we hadn't scored in about 8 months at home.
I'm sure there are more but those ones stand out for me in recent years. Nothing will ever come close to Aguero winning the league though. Bodies flying everywhere, fans hugging, crying, some just stood there in pure shock, never seen anything like it. Think I remember reading an interview with Mark Hughes not long after that game and when asked what he thought of it, he said he has never heard a noise like it inside a football ground, deafening I think was the word he used, literally exploded when that went in. What memories!
