NEWLY-APPOINTED Fremantle coach Justin Longmuir wants to make the Dockers a "great football club" during his time in charge of the club.

Longmuir was on Monday unveiled as the new Dockers coach for the next three seasons and the former Fremantle player says he can't wait to get started.

"I am looking forward to getting to know the staff at the football club," Longmuir said.

"I would like to thank Freo for this opportunity...so let's get to work and make Fremantle a great football club."

While reluctant to declare where he thinks the Dockers can finish next season, Longmuir said there was no reason why they shouldn't be aiming for the ultimate success.

"I am in it to win premierships," he said.

"I want this footy club to be great for a long period of time."

Fremantle president Dale Alcock said Longmuir was a standout candidate and he had no hesitation in appointing him.

"Justin stood out for us as someone who has been preparing for this role for over 10 years,” Alcock said.

"He knows what is required to win and what is required for sustained success.

"He is someone who is genuine and driven to get our players to the best they can."

The Dockers made the decision to appoint Longmuir late last week but wanted to wait until after the Grand Final to reveal publicly.

The 38-year-old was seen as the early favourite in the hours following Ross Lyon’s sacking last month after the Dockers had monitored his progress for several months. 

Longmuir won the job ahead of former Docker and Bomber and current Gold Coast assistant Dean Solomon. 

He played 139 games for the Dockers from 1999-2007, retiring as a 26-year-old and turning his hand to coaching.

Longmuir started as a development coach at West Coast in 2010 before stepping up to line coach and was part of the Eagles’ 2015 Grand Final campaign.

Targeted by several clubs at the end of 2017 including Adelaide, he chose to move to Collingwood on a three-year deal ahead of 2018.
