Ralston will now be hoping that he can continue to impress in the youth ranks and make his breakthrough into the Celtic first team before too long.

He brought through the likes of Raheem Sterling, Joe Gomez and Jon Flanagan during his time with the Reds and Ralston will be keen to make a similar breakthrough at Paradise.
