Their wins against them are that rare that I think I can actually remember all 7 wins. I can remember 8 actually so that stat doesnt look accurate.
From memory:
2001/02 - Think they won 1-0 up there with Darren Mackie scoring
2004/05 - They won 3-1 at Parkhead which ended Celtic's long unbeaten run at home in the league.
2008/09 - Zander Diamond scoring the winner in a 4-2 or 4-3 win.
2009/10 - A similar game to the one the season previousIy, I think it maybe have been a 3-2 win.
2015/16 - Two home wins, both 2-1.
2017/18 - Last game of the season, Celtic threw it so Aberdeen could finish second which ultimately backfired as they drew Burnley in Europe and went out. Burnley at that time may have caused us issues that early into the Gerrard reign.
They also knocked them out of the Scottish Cup in 2013/14 after a replay so that would be 8.
