Mackay said, "Alexander is a young midfielder that I had tracked for a few years here with Scotland. His father played for Dundee. He can play for Scotland, England, Australia and, I believe, Peru.
“We had a meeting with Alexander and his mum, dad and family four years ago about coming to play for Scotland.
“I've been trying to tempt him for four years as performance director to come and play, so I have managed to get him in a slightly different guise to come on loan to Ross County and I'm delighted.
“We had a really good conversation with Manchester City and their recruitment and loans department and they felt it was a good environment to get him into. I'm delighted to get him.
“He actually had a grounding at Man United before going over to City. If you've had four or five years at those two clubs then you've got a good start. The big question, as always, is can that potential turn into talent?
“Top young talent go on to play against men. It certainly helps when you have been training with Man City's first-team."
