Has to be the infamous Scott Mcdonald double when they chucked the league.
I was in my local boozer (mixed support) and had taken no end of pelters and had to endure them singing and dancing all through the match (or at least 80 minutes of it). After his first goal I didn’t even turn around (the boozer had the poet game on one big screen at one end, and our game on a big screen at the other end). Up until he scored his second, I was still sure they’d come back to win, so I didn’t take the opportunity to gloat.
Needless to say, the gloating soon started.
Looking back, I’ve no idea why I even went in the boozer before the game, or why I stayed when they went 1 up. I had absolutely zero belief that we were winning that title.
But boy am I glad I did. I don’t believe in omens or the like, but something somewhere tells me I went that day for a reason, despite being a non-believer
