Martin O'Neill and Alex McLeish have paid tribute to former colleague Tommy Burns, who died yesterday morning after a long battle with skin cancer.
The 51-year-old former Celtic and Scotlandstar worked alongside O'Neill during the Aston Villa boss' time as manager with Celtic and McLeish played against him many times during his playing career with Aberdeen.
O'Neill, who was manager at Celtic Park between 2000 and 2005, said: "I am deeply sorry to hear news of Tommy's death. I met him in June 2000 when Ibecame the Celtic manager. He was a great help to me in those early weeks at Celtic Park.
"I entrusted Tommy with the job of redeveloping Celtic's youth policy and when I joined him in visiting the families of prospective players, to persuade them to join Celtic, Tommy was always treated with reverence and respect. He was a brilliant footballer and will be very badly missed. My condolences go out to his wife and family."
Birmingham City manager McLeish said Burns was 'a proper player' and he would have loved to work with him when he took over as Scotland manager.
"One of my first jobs given to me by Sir Alex Ferguson when I broke into the Aberdeen side was to try and mark Tommy at Celtic Park," McLeish recalled. "It was a privilege to be asked to play for Aberdeen and then to be asked to mark Tommy was an honour. He was a key player for Celtic and Sir Alex always singled him out for a marking job. We grew up together in the Scottish football.
"He was a gifted left-footed player and like most left footers he was very easy on the eye to watch. He was a humble guy and a great role model for modern footballers. He was never fazed by anything, was always positive and he had fantastic humility.
"When I took over from Walter Smith as Scotland manager I would have liked to work with Tommy but he decided to put everything he had into his coaching role at Celtic.
"When a new manager comes in, if you inherit a coach like Tommy you were very lucky. I would have loved to have worked with him. He was the kind of person you wanted around you."
Gordon Strachan, the current Celtic manager, knew Burns well and was emotional as he paid tribute to his friend.
"He radiated every time he walked into a room, however you were feeling you felt better when Tommy was about, and we will miss him. It's not the same when he's not here," he said.
"The best thing I ever did when I came here was make Tommy assistant manager, for his intelligence, common sense and humour. He kept me sane at times, it was just a privilege to be in his company every day.
"There is absolutely no doubt about it I have laughed every day since Ijoined Celtic. His memory will make me feel good now he's not here."
Former Aston Villa striker Alan McInally, a former team-mate of Burns in the national team, said: "It was a privilege to know Tommy Burns.
"Tommy's passing will be mourned by the entire Celtic family. He will be hugely missed by us all, but he is someone we will never, ever forget."
Burns had been undergoing treatment in both Glasgow and France in recent weeks after being diagnosed in March.
