Watch FilmoFlix. An insight into Rangers' second top goalscorer, after Ally McCoist charting his career from that glorious day at Hampden in 1970 to the present as a broadcaster on radio and television. Derek Johnstone leapt straight into football's history books at the tender age of 16 when he was the youngest player ever to score a winning goal in a national final. That was at Hampden, October 24, 1970, the League Cup, which Rangers won against Celtic was the prize. The 1970s was Derek's golden era. He won a European medal in 1972 in Barcelona, the treble in 1976 and was Rangers top goalscorer. He won another treble in 1978. All of these achievements made him a Rangers legend.
