Zak is a left-footed centre-half who is a powerful figure both in the air and on the ball, capable of handling himself among most types of strikers.
He has represented Scotland a U19 level having already reached the UEFA U17 Championship semi-finals with his country.
He’s one that will go from strength to strength; a great physique, good speed and has a lot of the required criteria to be a centre-half.
He was handed squad number 22 for the start of the 2016-17 season, having played a role in pre-season preparations out in Oosterbeek, Holland.
