Fremantle coach Ross Lyon says the appearance of a West Coast spy at Dockers training this week wasn't a good look - literally.
With Fremantle well and truly out of the finals mix, the build-up to Derby XLIV has been relatively low key.
But that didn't stop Eagles scout Tim Gepp taking a look at Dockers training on Wednesday.
The first 20 minutes of the session was open to the media, but it was closed from that point on.
It's unclear how long Gepp stayed for, but Lyon was all too happy to poke fun at the Eagles employee on Thursday.
"He was still on his exercise bike. Can you get him out of the lycra please? It's not a good look," Lyon joked.
"He was wearing his West Coast jumper too I think," Eagles coach Adam Simpson chipped in with a chuckle.
For the record, Gepp wasn't in his lycra gear on that occasion, but he's been known to frequent Dockers training on his bike from time to time.
West Coast held a closed training session on Thursday, and Lyon said the Dockers wouldn't have prying eyes in there.
"I think Nizzy (Eagles chief executive Trevor Nisbett) runs a pretty tight ship, so we respect the anti-spying laws," Lyon said.
"So we won't be able to get anyone in."
West Coast (12-6) need to win on Sunday in order to keep their top-four hopes alive, with last week's shock loss to Collingwood dropping them to sixth.
Fremantle (3-15) will be aiming to bounce back from the disappointment of last week's 90-point loss to Sydney, which came in Matthew Pavlich's 350-game milestone.
