I don’t believe ISS has any u21mins yet , but that will come soon . The Echo describes him as a left back and impressed Baines playing in his old position, but as far as I can tell all his u18 games this season have been as a centre back , usually with “5” on his back. He is though one of those players who looks comfortable at left back , and left centre back in a 4 or 3 , and its likely that his first progression with the first team will come as a LB.
