The only goal I have never cheered properly was Augero 9320. As the move built up it was like watching a film (like an out of body experience). When he scored I slumped down into my seat in a state of shock. I just watched the hysteria going on around me. It was a state of pure bliss. Almost spiritual. I didn't really start cheering till I was in the pub two hours later. This is what football does to you. And the person who wrote that hate-filled bile about our fans being "subdued" will never understand that feeling. Perhaps that's why he doesn't connect with his football-loving family (as he implied in the article).
Whilst we're still doing these, my first thought when the ball hit the net was "it'll be offside or something", desperately trying to see the linesman on the far side from us to see if his flag was up. Then realisation that we'd done it, and total hysteria set in - I just stood there laughing hysterically and realised that I just could not stop laughing. Don't think the enormity sunk in until the 44 years banner was played on the scoreboard...
CL - different as watched it on TV practically alone. But still can't begin to describe the feeling of winning the CL as anything other than fabulous.
