Ange Postecoglou says there is even more to come from the revitalised Anthony Ralston.
And the Celtic boss is also tipping his countryman Tom Rogic to keep firing and scale even greater heights as a Parkhead hero.
Postecoglou is successfully mixing old and new as his team gathers momentum.
Signings such as Kyogo Furuhashi and Jota have lit up Glasgow's East End, but other individuals who’ve been in the building a while longer are playing their part.
Ralston has been a revelation. At the beginning of the season, he was the Aussie’s only available option for right-back.
Now his performances mean the gaffer is happy enough to switch £2.5 million Croat international capture Josip Juranovic over to the left.
Ralston’s displays have been a huge boost and, with talk of a new contract in the offing, the boss has saluted his desire to grab a second chance and says there is more to come.
He explained: “I don’t think he’s thinking about contracts. The important thing for Tony is to keep doing what he’s doing.
“Every week he works hard and wants to improve. He’s having an impact in games.
“Like all footballers, when they do those things, the rest of it takes care of itself, contract issues and all that kind of stuff. I’m sure he’ll get rewarded.
“Other people might have a different opinion of him, but, from the moment I walked in, all I’ve seen is a footballer who’s really eager to learn.
“He really wanted an opportunity and really wanted to take it. As a manager, that’s what you are looking for.
“You want guys who will give everything for that opportunity, who want to learn, be better and who demonstrate that every day in training, not just in games.
“Tony is one of those guys.
“Sometimes in a football career when there’s uncertainty or it looks like something could be taken away from you, getting a second bite at it makes you even more determined to get it right.
“He’s done everything right so far. I think there’s more to come.”
Rogic is another whom Postecoglou expects to keep raising the bar.
The playmaker is a veteran of Parkhead having joined eight years ago and has been an outstanding contributor to special trophy wins.
However, Postecoglou refuses to accept Rogic can’t go even higher and is confident he can keep pushing on alongside David Turnbull through a gruelling spell of activity.
He said: “He’s just got something different about him.
"Yes he’s had some issues, but sometimes I think he’s one of the players who people want to put in a certain box.
“Throughout his career, he’s done some remarkable things. He’s had a fantastic career here with Celtic. You don’t stay at a football club like this unless you have something to offer.
“I still think there’s more to come. He’s only 28. In many respects his best football years could be ahead of him.
“He’s now beyond the 50-cap mark with Australia which isn’t easy. To travel from this side of the world to play is a lot more challenging than maybe some other national teams.
“He’s done remarkably well. He’s become a senior member here at Celtic and with the national team. He’s got plenty to offer for both teams.
“Since I’ve been here, knock on wood, he’s done everything right on and off the field.
“I think he’s looking strong in games. In some games we’ve taken him off only because we’ve wanted to change the dynamic a little bit rather than due to fitness.
“Him and David have played a lot of football so far. We’ve just got to be careful with them not to tip them over the end.
“We’re working hard with the sports science staff to make sure we are keeping track of their workloads.
“At the moment, they are both still really strong and looking bright in games.
“That’s pleasing for us because both players can make a big impact when they are on the field.
“I know Tom well and have always felt that he’s got something special about him.”
James Forrest and Christopher Jullien will soon be other older faces returning, whilst Mikey Johnston has further boosted attacking options with recent sub outings.
Postecoglou said: “The important thing for Mikey now is he’s had two or three weeks of really solid training.
“The key is that he keeps getting stronger and working hard at his game on and off the field. I’m sure his opportunity will come.
“The pleasing thing about last weekend was that we could give Liel [Abada] a bit of a breather.
“Being able to even then take Kyogo, Jota and Giakoumakis off knowing we had some options on the bench like Mikey, Liel and Albian Ajeti was pleasing.
“Giving our front players a bit of a rest has been probably the one area we’ve really struggled with. Not just between games, but during games.”
Postecoglou will need all his stars shining at Easter Road, despite Hibs losing their last two games.
The manager said: “They have had a little bit of a dip, but they aren’t in crisis by any stretch.
“We’re expecting a tough test there, we’ll have to be at our best.”
