The 17-year-old was an integral part of last season’s U18s FA Youth Cup-winning team.
Born in Lancashire, Clarkson has been at the club's Academy since U8 level.
A creative player, he often acts as the anchor in midfield, where he can display an impressive range of passing, as well as showing his talent from dead-ball situations.
Clarkson made his U18s debut as an U16 player in 2017-18 and was a regular for both the U18s and U19s in the UEFA Youth League last term.
