is an English former international football player, manager and pundit. An attacking left-sided winger, his playing career spanned 19 years and took him to 25 clubs across eight countries. He is the son of Ken Barnes, who won the FA Cup with Manchester City in 1956. An England Youth and under-21 international, Barnes was a member of the UEFA European Under-19 Championship winning team in 1975. He won 22 senior caps for England, scoring four goals. Though he was never selected in a squad for a major tournament, he played in two victorious British Home Championship campaigns.

Barnes began his career as an apprentice at Manchester City in July 1972 and turned professional two years later. He made his Football League debut in October 1974, aged 17. He scored in City's 1976 League Cup final victory and was named as PFA Young Player of the Year. He played in the UEFA Cup and unsuccessful First Division title campaigns, scoring 22 goals in 151 appearances in all competitions. He became West Bromwich Albion's record buy at £748,000 in July 1979 and spent two seasons at the club, scoring 25 goals in 92 matches. Leeds United broke their club record transfer when signing him for £750,000 plus £180,000 \"tariffs\" in 1981. The move proved to be a poor one. After Leeds were relegated into the Second Division, he was bought by Spanish club Real Betis for £300,000. He made 16 La Liga appearances, scoring one goal, before returning to Leeds United for the 1983–84 season.

Barnes was signed by Coventry City for £65,000 in October 1984 but was dropped by the end of the 1984–85 campaign. Former West Bromwich Albion manager Ron Atkinson then signed him for Manchester United for a fee of £30,000, and a run of good form prompted speculation of a return to the international fold before he suffered a calf injury in November 1985. He was sold to former club Manchester City for £20,000 in January 1987, but he failed to establish himself in the starting eleven. He spent the next five years moving from club to club, never featuring more than eleven times for the same team. After his retirement, he briefly managed Conference club Runcorn. He had numerous jobs, including working as a television and radio pundit.
