Matthew joined the U's on loan from Millwall until the end of the season in January 2015, before converting his move to a permanent one in the summer of the same year.
Primarily a left back, he has also played at centre back in his professional career so far. The 23-year-old was the youngest ever Premier League player when he made his debut for Fulham at just 16 years and 65 days.
Whilst with Fulham, he had loan spells at Leyton Orient, Peterborough United, Bristol City and Watford, before joining Millwall in the summer. Having enjoyed his loan spell with Colchester in 2014/15, it was no surprise to see him return to the Weston Homes Community Stadium as a full time player.
