Pundit moots dressing room doubts over Postecoglou after Celtic 'embarrassment'

Noel Whelan has insisted Ange Postecoglou will have to win over certain players in the Celtic dressing room after being appointed manager. 

The former Aberdeen striker, speaking exclusively to Football Insider, suggested some Hoops stars would be questioning the 55-year-old’s arrival at Parkhead.

Celtic confirmed Postecoglou’s appointment on Thursday (June 10th), with the former Australia boss committing to a 12-month rolling contract.

Celtic finished 25 points behind Rangers in the hunt for the Premiership title last term.

Whelan admitted last season was an “embarrassment” for the Bhoys.

He insisted Postecoglou would have to convince the squad things would change next season.

Whelan told Football Insider’s Russell Edge: “The first job is you’ve got to assure the players that what happened last season will not happen this year.

“You need to get them behind you and show them that confidence and belief in the manager. That’s the first thing because I’m pretty sure they’ll be wondering who this guy is as well. You’ve got some big personalities there, international players.

“You’re going to have to get these more experienced players behind you. You’re going to need them in the changing room if things aren’t going smoothly. Look Celtic should be winning the majority of their games, no matter what, in that division.

“It’s the embarrassment of how far they were behind Rangers and everything around the manager appointment. Where Rangers are right now, they’re in a real good place. There’s a lot of pressure on him to hit the ground running at Celtic.” 

Postecoglou’s only previous experience of managing in Europe was a ten-month spell Panachaiki in the Greek third tier.

He spent four years as Australia boss before joining Japanese outfit Yokohama F. Marinos.
