Carlton is monitoring the situation surrounding in-demand Collingwood assistant coach Justin Longmuir, according to Mike Sheahan.

Longmuir is a leading candidate to secure the vacant senior coaching role at Fremantle having enhanced his credentials specialising in backline and team defence at the Magpies.

The 38-year-old served as a development coach at the Dockers before joining arch-rivals West Coast in 2011, spending the next seven years under John Worsfold and Adam Simpson.

Sheahan understands the Blues would like to partner Longmuir with senior coach David Teague for 2020.

“If he (Longmuir) misses out on Freo, Carlton are very, very keen on Justin Longmuir,” Sheahan told SEN Breakfast.

“Carlton refuse to finalise their coaching support panel until they know what’s happening at Freo.

“Right now, if I was punting, I’d say he’s going to end up at Carlton.”

Carlton bolstered its football department with Henry Playfair (Head of Coaching Performance) and Luke Power (Head of Development) joining Teague at Ikon Park.
