We look ahead to this weekend's League Cup Semi Final on Celtic TV.
The Welsh internationalist joined Celtic in the summer of 2011 on a pre-contract agreement from Cardiff City.
Despite his tender years, and fierce competition for the right-back berth, he swiftly become a key member of the squad. The defender bagged his first goal for the club in December 2012 during a Scottish Cup win at Arbroath, and he has now made over 100 starts for the club.
A product of Cardiff City's youth system, Matthews broke into their top-team aged just 17. He went on to play over half of the club's first-team matches in the 2009/10 season, attracting interest from several Premier League clubs - but Celtic would win the race for his signature.
The defender has become a firm favourite with the Celtic support, for his reliable defensive displays as well as his ability to play further up the park as a right winger.
Matthews had a stop-start season 2013/14 due to a series of injuries, but he returned to action to help Celtic clinch a third league title.
Under Ronny Deila, Matthews has continued to thrive for Celtic, bagging his first goal of the season with a wonder strike away to Hamilton.
