John Worsfold has taken up a consultancy role with Carlton.
Worsfold, who finished up as Essendon coach last year, will work closely with David Teague and his coaching group as a mentor.
The West Coast premiership coach commenced his career in the caper with the Blues back in 2000 and has previously worked with Teague at the Eagles.
“Our coaches demand that our players are doing everything they can to get better, they also have that same expectation on themselves, which is driven by our Senior Coach,” Carlton’s head of football Brad Lloyd said in a statement.
“We’ve been in discussions with John for some time, given his existing relationship with David, so it’s terrific to now have this finalised and is another step forward in our commitment to bringing success to the Carlton Football Club.
“David and John have maintained their connection since their initial time in Perth and as part of David’s personal development, John will observe a couple of games this year in a mentoring capacity.
“We are really pleased to be able to formalise that mentorship to now benefit the entire coaching staff.”
Worsfold, who returned to Perth after his time with the Bombers, will consult by being in “regular contact with the coaching group”.
The Blues host Brisbane at Marvel Stadium this Saturday.
