Morley won six caps for England, but his career fell into decline after not being picked for any of their games at the 1982 World Cup. This despite the fact that England boss Ron Greenwood supposedly favoured attacking football. He failed to score in any of his six senior appearances for England, his first cap occurring on 18 November 1981 in England's 1–0 World Cup qualification clincher against Hungary, the last coming almost exactly a year later when he took to the field in a Euro 84 qualifier against Greece which England won 3–0. Morley was not selected for the England squad for the 1982 World Cup in Spain, with Greenwood opting for Arsenal's Graham Rix instead.
