The following season, Rangers and Celtic shared a cup triumph each, beating the other in the finals; Celtic gained revenge in the League Cup before Rangers won the 1965–66 Scottish Cup 1–0 in a replay, with Wilson playing at inside left in the matches to accommodate both him and Johnston in the team. Ten days before the League Cup Final, on 13 October 1965, Johnston had made his debut for Scotland in a World Cup qualifying fixture against Poland, aged just 18; the match would end with disappointment in a 2–1 home defeat, the opponents scoring both their goals in the last five minutes.
