Wing signed for Scottish club Dundee United in January 1965, joining former Örgryte teammate Örjan Persson, who had made the same move the previous month. Wing's debut for the club was in a Scottish First Division match against St Mirren on 23 January 1965. He went on to be a regular in the left half position for United over the next two and a half seasons and was part of the team that eliminated holders Barcelona from the 1966–67 Fairs Cup.
