For Allen, one of the British division's most recognisable fighters, it represents a test against a man whom he sparred with at the start of the latter's professional career.
But Barker feels the 32-year-old will need to put on a show at the Kingdom Arena, and hopes he can leave everything in the ring for what could be the last big bout he faces.
"He said he will find out on Saturday," he said on DAZN's broadcast of the Open Workouts. "It is mad to think this man is only thirty-two, with the people he’s been in with, how long he’s been around.
"He’s been in some big fights. This man has underachieved. He’s never won a title, any title, nothing. He’s fought for titles, but he’s never won any.
"He’s good enough to win a solid domestic title. He’s got quick hands, he’s tough, he’s got the heart of a lion, he’s got good footwork.
"But for whatever reason it is, he just hasn’t transferred it into the ring on fight night.
"What I want to see from Dave Allen is just him completely empty the tank. Give it everything, with one last roll of the dice. Let’s see what happens."
