Celtic said in a statement Thursday morning: “The whole Celtic family is mourning his passing, and everyone associated with the club sends their thoughts and prayers to his family, his fellow Lions and his many friends at this desperately sad time.” Gemmell, who was capped 18 by Scotland and played in the 3-2 win against World Cup winners England at Wembley in 1967, also scored in the 1970 final when the Hoops lost to Dutch club Feyenoord.

And, like the rest of the Lions, Tommy remained humble about his incredible football achievements.” Dozens of tributes have poured in. Former Celtic Murdo MacLeod called Gemmell's passing "very sad news," and described Gemmell as "one of the greats." Celtic’s chief executive, Peter Lawwell, said: “Tommy was a Celtic great, one of football’s greats and I know he will be so sadly missed by everyone who knew him. He was a man of huge stature in the game and someone who made such an important mark on Celtic Football Club. “Tommy will forever hold his rightful place as one of the true Celtic legends. In this particular year it is so very sad to lose such an important figure – while we mourn his loss, I am sure all our supporters will also celebrate the life and the wonderful achievements of the great Tommy Gemmell.” ?️ Celtic Chief Executive, Peter Lawwell: "It's a deeply sad day.
