THE TOP eight is set for season 2021.

Fremantle's failure to defeat St Kilda on Sunday meant that Essendon were locked into eighth place without needing to beat Collingwood later in the afternoon.

The match-ups for week one of the Toyota AFL Finals Series are now locked in, with the venues and timeslots still to be confirmed.

The two qualifying finals will see top-of-the-table Melbourne take on fourth-placed Brisbane, while second-placed Port Adelaide will host third-placed Geelong.

In the two elimination finals, the fifth-placed Western Bulldogs will face eighth-placed Essendon, while sixth-placed Sydney takes on fierce rivals and seventh-placed GWS.

The final round of the home and away season produced the most exciting finish in history after an incredible Saturday evening. 

LADDER PREDICTOR Where will your club finish?

After Port Adelaide defeated the Western Bulldogs to seal a top-two spot on Friday night, Brisbane jumped into the top four on Saturday after beating West Coast by just enough points in the final minute. 

But that drama was nothing compared to the battle for the minor premiership with Melbourne producing a comeback for the ages to defeat Geelong after the siren. 

Greater Western Sydney also sealed its finals spot after defeating Carlton in Eddie Betts' final AFL game.
