Kane Cornes believes just six teams have the opportunity to lift the premiership cup in 2020.

While speaking on SEN on Monday, Cornes broke all the AFL teams into three different groups of six; teams that can win, teams that can't and teams that are in the finals mix.

In the six teams that can take home the cup, Cornes named all four preliminary finalists of 2019 (Richmond, GWS, Collingwood, Geelong) as well as the Western Bulldogs and West Coast.

In doing so, Cornes left off Brisbane, who did enough to finish the home-and-away season in second place.

At the other end of the table, Cornes said Gold Coast, North Melbourne, Adelaide, St Kilda, Fremantle and Carlton don't have a chance at glory in 2020.

That leaves Hawthorn, Sydney, Port Adelaide, Melbourne, Essendon and Brisbane in the middle tier, fighting it out for the two final top eight spots.

Cornes gave some reasoning behind his top six selections, which can be seen below.

Cornes on Richmond:

“Richmond can clearly win it. They’re in as good a shape as any team in recent memory to go back-to-back.”

Cornes on GWS:

“GWS can win it, no doubt.

“They got (Sam) Jacobs in, Callan Ward back, get Toby Greene and Josh Kelly fit, Jeremy Cameron is in his prime. They got two further top-10 draft picks to add to their talent.

“(Stephen) Coniglio fit, Giants can win it.”

Cornes on Collingwood:

“Can win. They’ll be thereabouts.”

Cornes on Geelong:

“Even though they lost Tim Kelly, one of the best midfielders in the competition.

“They get Jack Steven, he’s got rid of that pot belly, he looks fit. (Josh) Jenkins will be handy. (Patrick) Dangerfield, (Joel) Selwood and (Tom) Hawkins still with some good footy left.

“I know their finals record is poor but I still think they can win the flag.”

Cornes on Western Bulldogs:

“They have a list capable of winning it.

“Josh Bruce and Alex Keath plug some holes for them and their midfield is as good as any in the game.”

Cornes on West Coast:

“The addition of Tim Kelly maybe gives them the best midfield in the comp.

“Jack Darling is emerging as one of, if not, the best high key forward in the game.

“Highly dependent on the fitness of (Nic) Naitanui, Josh Kennedy and Jeremy McGovern just how far West Coast can go.”
