Port Adelaide coach Matthew Primus says the change of coach at AFL rival Adelaide is irrelevant to him.

"It means nothing, coaches versus coaches ... it doesn't matter who is sitting in the coaches box," Primus said.

Port on Sunday meet the Crows, to be coached by Mark Bickley for the first time following Neil Craig's resignation.

Primus last year was in an identical situation to Bickley, when he replaced Mark Williams as Power coach with seven games remaining.

But he offered just one tongue-in-cheek piece of advice to Bickley at a joint media conference on Friday.

"Don't win your first game," Primus said.

The Port coach expected Bickley to implement some changes, but said coaching won't decide Sunday's clash.

"Tactics and throwing things around and all that kind of stuff is a bit of a myth in footy," Primus said.

"Your structures are what hold up, and it doesn't matter the names that you put down - it's the amount of ball you can win and the pressure you can put on the opposition, it's pretty simple.

"We expect a few different things, but we'll be prepared."

Port enter Sunday's encounter in last position with just two wins; Adelaide faring little better in 14th spot with four wins.

"The state of footy (in South Australia) isn't great, where we are positioned on the ladder," Primus said.

"But the exciting thing is two clubs are having a look at their future lists.

"The clubs are battling away through some tough times at the moment but ... we can look this as the start of new eras for both football clubs."
