On 14 August 1971, 20-year old striker Kenny Dalglish scored his first competitive goal to help Celtic past Rangers in the Scottish League Cup.
Dalglish (pictured, top left) started his professional career with Celtic in 1968, but made only nine total appearances in his first three seasons. But he impressed manager Jock Stein in a friendly played in May 1971, scoring six times in Celtic's 7-2 win.
Stein rewarded Dalglish with an appearance in their opening match of the Scottish League Cup, played at home against rivals Rangers (who had beaten Celtic in the tournament final the previous season) and Dalglish justified the decision by scoring from the penalty spot in Celtic's 2-0 victory.
Celtic went on to reach the final, where they lost to Partick Thistle. But they won the league for the sixth straight season (and would go on the win it the next three seasons as well). Dalglish provided a total of 23 goals that season en route to a grand total of 167 in his Celtic career, which ranks him 10th on the club's list of all-time scorers.
Before he retired in 1990, Dalglish amassed a total of 366 goals for Celtic, Liverpool, and Scotland. In 2009, FourFourTwo magazine named him British football's greatest post-war striker.
