Sean is a left-footed central midfielder who joined Manchester United in the summer of 2012 from Exeter City where he'd been for 8 years. He had a trial spell in the spring of 2012 when he joined a young Manchester United side at the Aegon Future Cup in Amsterdam.
Sean became a regular in the Manchester United Under-18 team in the 2013/14 season with consistently good performances. He is a genuine goal threat from centre midfield particularly if given space outside the penalty area.
Sean missed the majority of the 2014/15 season with an injury but returned and came into the side in spring 2015.
He started the 2015/16 season by joining the first team on their pre-season tour and was included as a substitute for the first time away to Watford in November 2015. Sean scored the winning goal for the Under-21 team against Liverpool in November 2015.
