Modest and measured in his personality, Sonni-Lambie’s progression since making the switch has been hugely encouraging.
He debuted for Liverpool U18s as an U16 player and has gone on to become a consistent source of goals and creativity within that team in 2024-25.
Having also earned a first call-up to England for the age group, he considers this season to be the most important yet of his fledgling career.
But with all that development, there has always remained an element of the Sonni-Lambie playing with his mates as a pastime.
He says: “If I had a day off, I’d just go and play football in the street with my friends. I just always wanted to play football.
“Street football, you just have loads of fun, a lot of skills. With street football, you just really do whatever you want. I still use a lot of skills in my game.”
That, therefore, explains Sonni-Lambie’s answer when asked if there’s a player he models his game on.
“He’s not really my position but I look up to Luis Diaz,” the 17-year-old replies. “He’s a very skilful player and he just excites me a lot. Just the way he can take on his man.
“I’ve always played in an attacking position. I used to play as a central attacking midfielder and I can also play off the left wing. But I’ve always been an attacking player.
“My best qualities I would say are definitely dribbling, driving with the ball and combining with my teammates in and around the box.”
