2010 St Kilda v Collingwood

The famous draw is one of the most heart-stopping games in history, and the last Grand Final to be replayed the following week.

Coming from seventh place on the ladder, the Western Bulldogs complete the fairytale by winning their first flag since 1954.

2018 West Coast v Collingwood

Collingwood kicks the first five goals of the game, but the Eagles storm back to record a five-point win thanks to Dom Sheed's heroics.
