Along with his domestic football appearances, Zak has been been capped by Scotland from Under-17 to Under-21 level, giving him a wealth of experience despite his fairly tender years.
Speaking via the club's official website, Zak said; "I am really pleased to be here at Walsall. I am buzzing to finally get the move over the line. I am looking forward to getting my head down and getting going now at the club.
"I am a left-sided centre-half and also left-footed. I am quite tall and quite quick so I think I am quite a presence on the pitch. I like to play football whenever I can.
"I like to bring the ball down and play from the back. Obviously, that can’t always be done and sometimes you’ve to go safety first.
"Last season, when I joined Macclesfield, it was all about survival and staying in the division and we managed to do that.
"It was a massive achievement for us, given the circumstances, but it is going to be a completely different task during my time here.
