I seem to remember applauding the goal Helsingborg scored against us, in a UEFA Cup match, a few years back. Although if I'd known it would turn out to be the goal that knocked us out of the competition, maybe I wouldn't have!
When Charlton beat us 4-3 a few years back on the last day, to stay up, Danny Mills got the winner. That wasn't applauded as such but I remember the Holte applauding the Charlton team/fans at the end for staying up.
I applauded a late Reading consolation goal at Villa Park in a 3-1 win a few years back with some considerable enthusiasm. I had a bet on 3-1.
Fuck that.
