Collingwood star Scott Pendlebury has bid farewell to assistant Justin Longmuir in typical tongue-in-cheek fashion.

Longmuir, who was today officially unveiled as Fremantle’s new coach replacing Ross Lyon, departed the Pies with the club’s blessing as he cut short his contract to take up to Dockers role.

Pendlebury took to social media to thank Longmuir for his efforts at the club.

“Well done Longy, quality person who’ll have a great impact over west,” he tweeted.

“We know he played at Freo because we’ve seen that match winning goal 20x in 2 years.

“All the best J-Lo.”

In a statement, Collingwood general manager of football Geoff Walsh commended Longmuir for his two years at the club where he helped build the Pies backline and team defence.

“Justin’s ability to build relationships and communicate with the players and his peers saw him have a quick impact at the club,” Walsh said.

“With his drive and commitment to further educating and bettering himself as a coach, it’s no surprise that he’s taken the next step in accepting a senior coach position.

“We look forward to watching him progress in his career and wish Justin and his family all the best for their new chapter.”

Longmuir has signed a three-year deal with Fremantle and has indicated structural changes at the club will be made under his leadership.

Fremantle general manager Peter Bell says he is looking forward to see what his former teammate can do.

“(Justin) always struck me as a really considered and thoughtful person and had some really strong philosophies and views on football,” Bell said.

“Thinking back to those years when he was a teammate, when you reflect on it, you could see there was a coach in there.”
