ADELAIDE coach Phil Walsh suggests Port Adelaide veteran Kane Cornes should keep quiet as Showdown XXXVIII approaches, after Cornes accused Walsh of copying the Power's game.

Speaking to Channel 10 during the week, Cornes said Walsh had taken elements of Port's game to West Lakes after he left Alberton last year to coach the Crows.

So similar were the two styles that Cornes believed his teammates knew "exactly" how Adelaide would try and play on Sunday.

"Out there they use exactly the same terms and the same style of play that we use at Port Adelaide," Cornes said.

"We know exactly what they're trying to do and what they're going to bring.

"AFL footy's funny that most teams copy what the good sides are doing so no doubt Walshy's a smart man and he's copied the parts of our game that he likes."

When asked about Cornes' comments at Friday morning's press conference at Adelaide Oval, Walsh delivered a typically stern and straight-faced reply:

"I think Kane should just stick to playing personally," Walsh said.

Cornes will run out on Sunday for the 27th time in a Showdown, equaling Andrew McLeod's record.
