Matthew, who is from Hartlepool, suffered a horrific shoulder injury at the end of the 2009-10 season but has recovered well. Before that he had been one of the outstanding players in his age group.
An all-action, energetic, tough and determined left-footed player, he can play in midfield or in defence and is an excellent header of the ball who has bags of promise.
He was awarded a four-year pro contract starting on July 1 2010 and established himelf as captain of Jamie Clapham's Boro U21 team.
He spent part of the 2012-13 season on loan at Yeovil and in August 2013 was loaned to hometown club Hartlepool.
