Despite being in the relative infancy of his professional career, Rathbone has ample experience of Sky Bet League One under his belt, having played over 150 matches in the third tier for Dale, including 40 appearances last term, in which he found the net three times.
Starting his career in the fabled Manchester United Academy, Rathbone played alongside the likes of current Red Devils stars Marcus Rashford and Scott McTominay, and won the club’s Goal of the Month Award for a sensational 40-yard strike for the Under 18s against Derby County in 2015.
