Port Adelaide president David Koch says the Showdown is the “greatest sporting rivalry in Australian football”.
The Showdown, which kicked off in 1997, is South Australia's flagship football event played between the Power and the Adelaide Crows.
The rivalry creates such a stirring atmosphere in Adelaide that Koch believes it exceeds any other in all football codes.
“I think we forget what an absolute privilege it is to be part of Showdowns,” he told SEN SA Breakfast.
“We get so tense, we get so grumpy about it or we get so focused.
“Arguably, this is the greatest sporting rivalry in Australian football across any code.
“The West Australians can have their derbies, Collingwood and Carlton can have their stoush but there is nothing like a Showdown and there never will be.”
Showdown 47 takes place at Adelaide Oval where Port Adelaide will aim to get revenge on Adelaide after losing by 20 points in the earlier game this season.
Koch's Power have lost seven of the last eight Showdowns.
