Midfielder Glen made his first-team debut in the League Cup third round tie away to Sheffield Wednesday in October 2015, a day before his 20th birthday.
After making 10 appearances for the under-21s, he returned to his former club Southend United on loan for the second half of last season. The Finnish Gunner made six appearances for the Shrimpers, and impressed with his tough-tackling and range of passing as Phil Brown’s side finished 15th in League One.
