The 17-year-old follows in the footsteps of Leo Thethani and Kiyaam Bull, who were also elevated from the development ranks in the past 12 months. The latter has since linked up with Dutch giants Ajax Amsterdam alongside Dean Solomons.
Matthews, who hails from Hanover Park, has been with the Urban Warriors since 2012.
He shone during Young Ajax’s tour to the Netherlands last year, making the 'Best XI' at the ICGT Tournament along with clubmates Renaldo Leaner and Luthando Mateza.
Matthews then represented the national U-18 side in August, scoring in a 2-1 friendly win over England.
