With Sydney and Geelong set to do battle in a blockbuster clash at the SCG on Thursday night, we thought we'd take a trip down memory lane and remember some of the best players that played for for both clubs.
We've also thrown in some obscure players that represented the Swans and Cats, for a bit of fun!
Here's our list: Greg Williams, Bernard Toohey, John Scarlett, Shane Mumford, Jason Mooney, Tony Malakellis, Simon Arnott, David Spriggs, Henry Playfair, Paul Chambers.
