I remember driving away from the Etihad after the Sunderland draw in 2012, and while stuck in traffic, some guy in a white van with Utd stickers & mobiles, on the other side of the road, was beeping his horn & shouting out of his open window & giving rude hand signals to all us City fans. Not sure if he was so sad that he'd purposefully jumped in his van & driven over to the Etihad just to wind us all up, but he was highly charged / ecstatic.
He obviously thought (as we kind of did too) that this was the final straw that showed we'd blown it & handed the title to Utd.
He was wrong. I give him a thought / like to imagine how he must have felt, whenever I rewatch the Aguerooooo moment.
