The 17-year-old, who has previously captained England at U16 level, initially joined the Reds' Academy from Arsenal in 2015.
Having subsequently risen through the ranks, he has featured prominently for Steven Gerrard's U18s team this term, catching the eye with a number of dynamic performances in central midfield.

"And [to do it] for the club that I've supported since I was born, it's a great feeling for me and my family.
