CELTIC legend Bertie Auld celebrates his 80th birthday today.

Here, we take a look back at his remarkable achievements on the pitch and in the dugout. 

Born in Maryhill, Auld first joined Celtic in March 1955 and went on to make more than 200 appearances for the club and help them become the first British side to win the European Cup.

After spending one season on loan at Dumbarton, the winger was sold to Birmingham City due to ill-discipline in 1961, where he went on to win the League Cup two years later.

Auld marked his return to Parkhead in 1965 and formed a midfield partnership with Bobby Murdoch under the tutelage of the great Jock Stein.

His return was a triumph as he secured six league titles, four Scottish Cups and five League Cups as well as starring for the Lisbon Lions against Inter, when he famously led a rendition of the Celtic Song in the tunnel before kick-off.

Auld ended his playing career with two seasons at Hibernian, when he began to become more involved in coaching, and he landed the Partick Thistle manager's job in 1974.

He stayed at Firhill for six seasons, winning the First Division title in 75/76, before returning to Hibs as manager in 1980, where he successfully led the Edinburgh club back to the top-flight following their relegation.

A spell at Hamilton Accies and a brief return to Thistle followed before Auld’s final managerial role came at Dumbarton in 1988.

In 2009, Auld was inducted into the Scottish football Hall of Fame in recognition of his achievements.
