Bradley was the only player with no previous senior club experience that took to the field for the Reds’ 30-minute friendly against Stuttgart.
While his academy colleagues Owen Beck, Leighton Clarkson, Jake Cain, Tyler Morton and Kaide Gordon took on Austrian second-tier club Wacker Innsbruck, the 18-year-old was trusted against Bundesliga opposition.
It was a glorified training exercise, but the Northern Ireland international acquitted himself well as Liverpool played out a 1-1 draw in Saalfelden.
Neco Williams, only just having returned from his post-season break, was an unused substitute, while Trent Alexander-Arnold captained a less-experienced side as Klopp showed trust in his latest academy graduate.
Bradley is widely considered as the next to step up into the first team, with Williams subject to transfer interest and Liverpool willing to part ways with their No. 76 for around £10 million.
And speaking to LFCTV after the game, Bradley admitted he was “trying to impress the manager” and “see what happens from there” as he hopes to establish himself at senior level.
“I just want to keep trying to better myself,” the teenager said.
“Trying to keep improving and trying to impress the manager the best way I can do. I just want to keep working hard and see what happens from there.”
Bradley said he was “incredibly proud” to make his first outing as he has “supported this club all my life,” having been brought up a Liverpool fan in County Tyrone.
It would be a big step for Bradley to move from the under-23s to backup for the world’s best right-back, but Klopp has shown he is willing to trust youth in the role with the promotion of Williams previously.
The youngster has made great strides since his arrival from Dungannon United in 2019, and having only turned 18 earlier this month he is already settled as first choice at U23 level.
“That’s obviously important as well for being a professional footballer: you look after yourself and look after the way you eat, how much you sleep, hydration,” he added.
“[I] watch how they do it and obviously learn from that.”
