CELTIC youngster Scott Robertson believes that Adam Montgomery's emergence at Parkhead proves Ange Postecoglou is serious when he says that age is no barrier to the first team.

The 20-year-old midfielder, currently out on loan with Crewe Alexandra in England's third tier, revealed that he and the new manager had a chat shortly after Postecoglou pitched up in Glasgow's East End.

The Greek-born Australian told Robertson and the other young players that they would be given first-team opportunities if they excelled in training, and Robertson says that the 56-year-old has been true to his word.

"From the first day the new manager arrived, he told us all that no matter what your age is, if you are good enough then you will play for him," Robertson told the Daily Record.

"It was great to hear him say that. He said we would get opportunities and I think he's shown that already with Adam's promotion into the first team that he's true to his word.

"I wasn't surprised to see Adam being thrown in at the deep-end so soon - nobody at Celtic was.

"The manager has shown he has faith in him and for a young player that is huge.

Celtic Way:

"He's shown by his performances so far this season that he's been up to the job and it's been an inspiration to the younger boys who see what can happen.

"It also shows the manager is someone who is prepared to look at the academy and give youngsters an opportunity.

"The big moment for Adam came when he was played in Europe against Midtjyland as a sub and he showed his temperament was strong enough to cope. Then he was excellent against AZ Alkmaar, he slotted right in and didn't look out of place at all.

"From day one the manager has been able to get his messages across very quickly, the points he wanted to make are well understood. He wants us to play football the right way, it's about keeping the ball and pressing high up the pitch.

"He wants to get the midfield players on the ball and for me that's been great as it's one of my strengths to get on the ball and pass it.

Celtic Way:

"From my point of view it has been brilliant. He doesn't like it when you take too many touches and end up having to go back the way. He wants you to get your head up as soon as possible and pass the ball through the lines."
