Essendon great Tim Watson believes Geelong and Port Adelaide deserve to be in the premiership conversation in 2020.

Watson responded to AFL coaching great Mick Malthouse's comments on theย Sunday Footy Showย that only six teams could win the flag - Richmond, Collingwood, West Coast, GWS, Brisbane and Hawthorn.

Speaking on SEN Breakfast,ย Watson said he felt there was an unnecessary amount of disrespect being shown towards Geelong's prospects this season.

โ€œGeelong should be in there (among the teams that can win the flag),โ€ Watson said on SEN Breakfast.

โ€œThereโ€™s two teams that should be in there and Port Adelaide is the other team I think should be in there too.

โ€œWhy is it that everyone feels itโ€™s compulsory to talk Geelong down or disregard Geelong in any way?

โ€œTheyโ€™ve been unbelievable, the fact that theyโ€™ve stayed around the mark.

โ€œEven last year they played against the best team in the competition (Richmond) and gave a great account of themselves in that Preliminary Final.โ€

Last year's minor premiers, the Cats have featured in 12 of the last 13 finals series, including four in a row.

Geelong reopen their season against Hawthorn at GHMBA Stadium on Friday June 12.
