Frank McAvennie claims Celtic could be repeating past mistakes after reportedly holding talks with Shaun Maloney.
The former Hoops hitman, speaking exclusively to Football Insider, questioned who is currently making the decisions at the club.
Last week, The Daily Record reported Celtic had held talks with Maloney over taking a coaching role at Parkhead.
Maloney, 38, is currently preparing for this summer’s delayed Euros as one of Belgium’s coaches.
He has been in the role since September 2018 after leaving his job with Celtic Under 20s.
As a player, Maloney won five league titles during his first spell at Celtic.
McAvennie has questioned who is making the decisions at Parkhead as there is still no manager in place ahead of the new season.
“It would be nice to see him back but it’s a surprise,” McAvennie told Football Insider correspondent Ben Wild.
“It’s Celtic doing the same mistakes again. Has the new manager signed off on that?
“This new boss will want his own team, even if Celtic want to bring in Maloney or keep on John Kennedy.
“If he’s worth his salt, he’ll say no. He should bring his own staff in.
“Maloney, I don’t think he’s ready for management but he’s one hell of a coach.
“The question for me is, who’s bringing him in? Is it the club or the manager?
“He won’t come in as the number four coach or whatever, he’ll want to be number two. “
A Celtic source has told Football Insider the door is open for the club to sign Ange Postecoglou to a contract and name him as their new manager.
He replaces Kennedy, who served as caretaker boss after Neil Lennon resigned.
