The defender made his B Team debut as a 16-year-old back in 2021 and has kicked on to a level where he was rewarded with a Scotland Under-19s call-up earlier this campaign.
An agile defender who is accomplished in possession himself, Allen says he draws inspiration from a treble-winning central defender currently plying his trade for Manchester City.
Speaking exclusively to the official Rangers website during the current international hiatus, the 18-year-old commented: “I don’t really think about one individual, but when you see players in the Premier League, their style of play is good.
“You look at someone like John Stones who stuck out last season. However, James Tavernier is someone who has been at Rangers since I first started going along to the games as a youngster and he’s been at the club for nearly ten years.
“You watch Stones in the Champions League and the role that he plays is amazing. It’s a role that I would want to play in the future, and he’s definitely a player that I look up to.
“I started off as a winger then slowly fell back to midfield before going one back and playing in defence. The next step is between the posts!”
Allen has featured regularly at the heart of defence this season as Gers B have embarked on a challenging games programme which has encompassed matches at home and further afield.
The teenager also impressed as the Light Blues dispatched Alloa Athletic to the tune of a 4-1 scoreline in the previous round of the SPFL Trust Trophy.
He continued: “You look at Manchester City, Manchester United, Monaco, and the other sides that we’ve faced this season, the standard is really high because we’re playing against clubs who are European giants. We need to stand up to it as Rangers are a big club as well and trust each other.
“When you play against Monaco, for example, they have players who represent France at their age group, while some have played for the first-team. You’re always getting challenged when you’re playing against European teams.
“The Alloa victory was really big. We were playing against a League One side and I thought the boys stood up to the challenge and got a good result.
“There’s been other games where the results haven’t quite gone our way but the performances have been good; OH Leuven was a strong test against a Belgian first-team and a good experience.”
International recognition has duly followed for Allen during his development in the Rangers Academy, representing Scotland at Under-17, Under-18 and, most recently, Under-19 level.
It’s experiences that will stick with the defender for a long time, and he hopes that training with the best at club and country can continue his development.
He added: “It was up there with one of the proudest moments of my career. It was nervy when I made my debut against Wales, but it was a proud moment when the national anthem first comes on.
“It’s a real goosebumps moment, especially with all your family in the stands, and it’s a brilliant feeling.
“You probably have three or four top players in every position who are the best in the country. The standard in training is always amazing and, when you go into games against Belgium or France for example, you can feel the belief in the squad.
“It’s always good to test yourself against other international players.”
