Celtic's domination of the Scottish league continued into the 1970s, and ultimately Johnston would end his spell at Ibrox without a championship medal. The 1970 Scottish League Cup Final went Rangers' way 1–0 over the familiar opponents, Johnston providing the cross for the winning goal, but he was fined afterwards by manager Willie Waddell for showboating (sitting on the ball), which supposedly brought shame on the club. The final of the 1970–71 Scottish Cup, yet another Old Firm clash, was won by Celtic after a replay. A major off-field tragedy had also befallen Rangers that year when 66 supporters died in a disaster at the stadium.
