The third week of finals is here, with the Demons, Power, Cats and Bulldogs remaining to decide the 2021 AFL Premiership.

The season so far has been full of drama and excitement, with there being no argument that the four best sides of the year are left to battle it out for the flag.

Between them we have the minor premiers in Melbourne, the interstate contenders in Port Adelaide, last year's Grand Finalists in Geelong and the underdogs in the Western Bulldogs.

Each club holds their own chance to secure premiership glory, with the race for the 2021 Premiership Cup made even more exciting thanks to your own bet365 promo code.

Will the Demons come out on top? Or will another minor premier fail to make it to the end? We grade each remaining finalist's case for the premiership.

Melbourne

The team to be beat, Melbourne capped off a stellar home and away campaign in style thanks to a post-siren match-winning goal from skipper Max Gawn to snatch the minor premiership from Geelong's hands.

Gawn, assisted by midfield duo Clayton Oliver and Christian Petracca, has led his side deep into this year's post-season, hoping to end the club's 57-year premiership drought.

Add in their pair of immovable backman in Steven May and Jake Lever, and it is easy to see why Simon Goodwin's side are fancied for the flag this year.

The Demons have shown little weakness throughout 2021, and will be hoping to tame the Cats once again this weekend in hope of securing a place in their first Grand Final in 21 years.

Port Adelaide

The Power stunned Geelong in their qualifying final, and will look to carry that form into this weekend's clash against the Bulldogs.

Ken Hinkley's men edged past the Dogs in a Round 23 thriller, and can only hope it is a similar story in their next matchup.

Their Grand Final dreams will be aided by a home prelim to host the Bulldogs, with the 'Portress' of Adelaide Oval set to play a key role in the Power's push for a premiership.

Should they advance past the Bulldogs, the Power will be hoping their form away from home doesn't come to haunt them, with the Grand Final set for Optus Stadium on September 25.

Geelong  

Throughout this year the Cats have fallen in and out of premiership favouritism, with recent defeats to fellow contenders Melbourne and Port Adelaide damaging their chances.

The two losses have placed Geelong behind the eight-ball, having to take the long route this post-season.

This avenue isn't unfamiliar to the Cats however, with a majority of their past finals series requiring an extra chance before moving closer to the flag.

Coach Chris Scott will be hoping his finals record and the over-bearing hoodoo that comes with it won't continue this season, with Geelong making just one Grand Final in 10 seasons despite their dominance.

Any chance the Cats have to break these chains will likely come from their key pillars in attack, with Coleman Medal winners Jeremy Cameron and Tom Hawkins looking to continue their strong runs of form.

Western Bulldogs

The Dogs are the only outside still in contention for the flag, having finished outside the top four and facing an uphill battle to keep their season alive.

A thrilling one-point win over the Brisbane Lions in last week's semi-final is sure to have ignited further confidence for the Doggies, who could match their historic successes of the 2016 season.

To do so though, they will be relying on the health of star midfielder and captain Marcus Bontempelli, who sustained a knee injury in Saturday's win over the Lions.

Should the skipper be fit and firing for the Bulldogs this weekend, they will stand a strong chance of causing an upset against the Power in South Australia and potentially adding another flag at Whitten Oval.
