Danny Mills has backed Ange Postecoglou to be a success as Celtic manager if his appointment is finalised.
Speaking exclusively to Football Insider, the ex-Premier League and England defender insisted his lack of experience in the European game is not relevant as a good coach will be able to transfer their methods.
Football Insider revealed on June 3 that Celtic are free to appoint the Greece-born Australian after agreeing compensation with his club Yokohama F. Marinos.
The Hoops turned to Postecoglou after talks with Eddie Howe broke down.
Celtic released a statement last Friday, May 28 claiming “for reasons outwith both his and Celtic’s control”.
“They’ve always done their due diligence and speak to a lot of people,” Mills told Football Insider correspondent Connor Whitley.
“They’ve had an eye on him, had a look at him and thought ‘Actually, this guy’s a good coach.’
“Why can’t he be good at Celtic? Mourinho had no real football pedigree, Arsene Wenger had no real football pedigree in terms of playing. Jurgen Klopp wasn’t brilliant as a player. You’d say he was very, very average.
“It is possible and why shouldn’t he? You’re either a good coach or you’re not. It doesn’t matter what system you’ve come through. If you’re a good coach, you’re a good coach. Nationality and pedigree doesn’t really come into it.
“They’ve obviously looked at it and thought ‘We like what he does.’ They’ve not just plucked a name out of nowhere because it’s very difficult to say to start with!”
