Danny McGrain, a pacy full-back, played at Celtic Park for two decades. "And he has been a model professional footballer since the first day he arrived," Jock Stein said of him.

McGrain spent a season with Queen's Park Victoria XI before Celtic signed him, dispatching him to Maryhill Juniors for six months.

His impressive performance as a youngster , training with Celtic, earned him a place in the "Quality Street Gang" - a group of young, enthusiastic players that also included David Hay, Lou Macari and Victor Davidson. Graduating to the first-team in 1970, McGrain would remain a dependable defender in Celtic's cause for many years to come.

However, his career was dogged with illness and injury. He suffered a fractured skull in 1972, discovered that he was diabetic in 1976 and was plagued with arthritis from 1977, after a foot injury left him unable to play for 18 months. Yet he overcame his problems to make celebrated contributions to Scotland's performance in the World Cup Finals in 1974 and 1982.

He won 57 caps for Scotland and at Celtic, he won five Championship badges, four Scottish Cup winners' medals and a League Cup winners' medal.

He was also voted Scottish Player of the Year in 1977 and was awarded the MBE for services to football in 1983.
