The 18-year-old joined the Reds' Academy from Stoke City at U13 level and has moved his way through the age groups.
He spent 2019-20 with the U18s, but was also involved with the U21s for the EFL Trophy and the U19 UEFA Youth League squad.
This season, Wales youth international Beck has been with Barry Lewtas’ U23s, continuing his development as an attacking left-sided full-back.
Beck agreed his first professional contract with the Reds earlier this year and has now committed to extending his stay with the club.
