The Man City cup game was a bit special. Still get shivers thinking about the noise from the Kop when Bish's header hit the net. I travelled down on a train full of City fans who were bouncing most of the way. I swear the carriage left the rails at one point! Good laugh though...

Rochdale home 2010 the x points and you f00krd it up chant!
I suppose these are 'most memorable' rather than 'best' games, but despite ending in defeat both times I will always remember them.
Going to the Sh!tty Ground in the cup game and matching them on the pitch and more than matching them in the stands was brilliant. Even losing on penalties didn't seem bad because at the time it gave us a sense of pride back. The other game is the extra time defeat at Anfield, and the moment Adam Coombes (fair play P4U) put us level after being the expected 2-0 down was just unreal. Fantastic day out, it was great chatting to Liverpool fans before and after the game and completely changed my opinion of them.
This was rather good as well.
Just had a look back at that Liverpool game, and to add a more surreal element their goalscorers were Raheem Sterling, Daniel Sturridge (2) and Jordan Henderson. Ours were scored by the mighty Yoann Arquin and Adam Coombes!
