Celtic legend Bobby Murdoch was Jack Charlton's sole signing in summer 1973 as he built Boro's record-breaking promotion team.
In Scotland he had won every honour, including the European Cup as part of the famous Lisbon Lions in 1967 and Player of the Year in 1969.
When he came to Ayresome Park he lacked the mobility of his Parkhead days, but his vision and passing were instrumental in Boro's success.
On his retirement in 1975 he was made youth team coach and when John Neal departed he was appointed manager.
But the team had been weakened by the loss of key players Mark Proctor, Craig Johnston and David Armstrong and the job was something of a poisoned chalice.
His first season ended in relegation after 17 years in the top flight and after a dreadful start to the next season he was soon on his way as Harold Shepherdson stood in as caretaker manager.
He died in Glasgow's Victoria Infirmary on May 15 2001 after suffering a stroke.
