Celtic supporters have been doing their homework on Scales and it's been noted by many that he has played in a variety of roles at his previous club.
And Scales believes his versatility could be key as he looks to offer Ange Postecoglou options across his backline with a flurry of key fixtures after the international break.
Speaking to Celtic's official website, he said: “Over the years I’ve played in plenty of positions. I suppose when I was younger I was a left-sided midfielder and I kind of dropped back. "At UCD I played mainly as a centre-back and I played a bit of left-back there as well, and in my first season at Shamrock Rovers I played centre-back.
