Fremantle Chief Executive Steve Rosich is confident the club has nothing to fear from investigations arising in the wake of Thursday’s Australian Crime Commission report on performance enhancing drugs in Australian sport.

Speaking at Patersons Stadium on Friday morning, Rosich said he had complete faith in everyone involved at Fremantle.

“We’ve got well respected and credentialed people in our sports science department,” he said.

“We’re very comfortable with our people, our structures and our processes, which very importantly involves experienced club doctors as well.”

Rosich said, as far as he knew, the ACC’s probe had not looked at Fremantle.

"The short answer is we don't know definitively, but every indication is from what we know that no, we weren't part of that,'' he said.

"Our club has a food-first focus, and the supplements are obviously part of that process, but they are only a minor part of it.''

The Freo CEO also said the club’s link with past sponsor Nutrition Systems, whose parent company was fined heavily for importing and supplying unregistered substances, ended for commercial reasons and that the club vetted all products it utilised.

"It was essentially a marketing contract," he said.

"It was a non-exclusive supply arrangement.

“There was a limited amount of product that we utilised from Nutrition Systems. In each of those cases the product was vetted by club doctors prior to the players using them.”

Rosich said the club would give the current situation in the AFL its due diligence, but that Freo were determined to stay focused on the task at hand, which was the upcoming NAB Cup and round 1 home and away fixture.

“We’re spending some time in this space to oversee our governance processes, which were very comfortable with, but our focus is on preparing for the season proper, both on the field and also commercially.

“We don’t get distracted.”
