Carlton great Mark Maclure has sent a warning to Carlton's board, saying a shake-up looms if they don't hire current caretaker David Teague as the full-time coach.

Teague has helped Carlton win five games from eight since taking over from former coach Brendan Bolton, and has received the blessing of fans, as well as past and present players.

Teague is competing with former Lions coach Michael Voss for the job, who was interviewed by the Blues last month.

Speaking on Fox Footy, Maclure said he was on board the Teague train.

“He’ll get the job. I think he’ll get the job,” Maclure said.

“What happens if he doesn’t get the job? What happens to the board then?

“They’ve made four or five ordinary (decisions) this century. They picked the last coach, he’s gone. What happens now … if they pick someone else and it doesn’t work?”

The club has gone through a list of coaches since the start of the century, with Wayne Brittain, Denis Pagan, Brett Ratten, Mick Malthouse and Brendan Bolton all being appointed then sacked.

However, Maclure said Teague knows the club and will help Carlton become ruthless again.

“This bloke fits really well because he knows the club now. He’s been there, played there, understands the scenario, the win-loss ratio type deal. We’re a ruthless club — not anymore — but we have been a ruthless club," Maclure said.

“I saw supporters after the (Eagles) game and there were waves of them saying ‘we’ve got to get this bloke’ … it was interesting.

“I think we need the best coach. To me if you haven’t got (Alastair) Clarkson, I’d take Teague."

If Teague was appointed as the full-time Carlton coach, it would be the second time this year a caretaker took over the coaching role full-time, following Rhyce Shaw becoming the next coach of the Kangaroos recently.

Maclure said Teague and Shaw were “just trying to fix their footy clubs — and I wish some of the other coaches would take a leaf out of their book”.
