I was born in Glasgow in 1955. During my career I won twenty international caps, scoring seven goals. My major honours included two League Cups, one League Championship, one FA Cup and one European Trophy. In 1977, I won both the PFA Players' Player of the Year and PFA Young Player of the Year awards. Who am I?
In this year, two foreign managers won their first ever trophies in England, a young Englishman won the PFA Young Player of the Year award and Manchester United signed a striker, breaking their transfer record. Name the year and the four individuals in question.
