Although often deployed in attack early in her career, Deighan made a name for herself as a midfielder. She scored in the semi-final of the
1984 European Competition for Women's Football, in which England reached the final before losing to
Sweden on penalties. Her final cap came in the
Mundialito in September 1985. Domestically she won the
Women's FA Cup in the 1979–80 season with St Helens, and reached three other finals as runner-up with the club during the 1980s. St Helens were beaten in the
1981 WFA Cup final by Southampton and in the
1983 and
1987 finals by
Doncaster Belles. She was allotted 21 when the FA announced their legacy numbers scheme to honour the 50th anniversary of England's inaugural international. ==References==
