After spending 33 years at the West Coast Eagles, former list manager and recruiter Rohan O'Brien has reportedly joined a new club for the upcoming season.

O'Brien stepped down from his role at the Eagles in December at the end of last year, shortly after drafting Harley Reid as the number one draft pick in the AFL Draft.

AFL's Callum Twomey has reported that O'Brien will take on a role with the Essendon Bombers and work on their scouting team as a recruiting officer.

His arrival at the Bombers will see him reunite with former colleague Craig Vozzo, the club's Chief Executive and former football boss at the West Coast Eagles.

Mainly focusing on junior football, his appointment comes after the club signed former AFL player Matt Rosa last September to their list management team as the AFL talent and operations manager.

It is understood that Matt Clarke (Richmond Tigers) and Michael Regan (Port Adelaide) have emerged as the frontrunners to take O'Brien's old job at the Eagles.

The club are reportedly in the final stages of negotiating with both, and a decision could be made shortly.
