I've done it quite a few times, including leaping out of my seat when Ched Evans/own goal went in, in the last minute at Midtjylland, but the weirdest one was at Maine Road. It was the last game of the season in '96 against Liverpool and I'd only decided in the morning whether I could face it.
Tickets were scarce outside and I picked up a ticket from a tout, about 10 minutes before kick off. It was 40 quid which was probably about three or four times the face value in those days. When he offered it to me, he said it was for the North Stand and I never considered it would be in the away section until I started looking for the block number. I sat there quiet for most of the game and only found out about 10 minutes from the end, that the lad sat next to me was also a blue. The scousers were quite humorous that day and were only concerned with what the rags were doing at Middlesbro. They all seemed to want City to stay up. I remember Rosler missing a header from point blank range and one of them said 'A man with no head would have scored that!' I had to agree and started laughing. I was thinking Christ, we're going down and I'm sat here laughing! We were pathetic that day! As the whistle blew, I thought Jesus, we are down and if the City fans start kicking off, I could get a battering outside as well. I had no colours on and was relieved to get away from the turnstiles and onto the Kippax car park and amongst other blues. What surprised me the most was that I 'd hardly said a word for the previous two hours and had no colours on yet when I left the ground, a scouser said to me 'I hope you come straight back up'. To this day, I'm still not sure how he knew I was a City fan. I'm sure some of you out there will have some answers!
