A club statement read: "Celtic legend Tommy Gemmell has passed away at the age of 73, and his death will be mourned by Celtic supporters and also the wider football world.

"A member of the legendary Lisbon Lions, Tommy scored Celtic’s equaliser that famous day, on May 25, 1967, as Jock Stein’s side went on to beat Inter Milan 2-1 and lift the European Cup, the first British team to do so.

"And Tommy was also one of the few players to have scored in more than one European Cup final, scoring again three years later in the 1970 final against Feyenoord in Milan’s San Siro Stadium.

"He spent 10 years at Paradise, between 1961 and ’71, making 418 appearances and scoring 63 goals. And as well as his two European Cup final goals, there were also 31 penalties. Indeed, he only missed three spot-kicks from the 34 he took in his career, a remarkable conversion rate."

It continued: "Tommy Gemmell is a true Celtic legend, part of the greatest side in the club’s history and a man who played a pivotal role in our greatest ever triumph when, in Lisbon’s Estadio Nacional, 11 men all born within a 30-mile radius of Celtic Park, beat Inter Milan to win the European Cup.

"The legend of the Lisbon Lions was created that night, and Tommy and his team-mates were assured their place in the pantheon of Celtic greats.

"And, like the rest of the Lions, Tommy remained humble about his incredible football achievements.

"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.

"Our thoughts are with Mary and Tommy’s family and friends at this very difficult time."

Celtic Chief Executive Peter Lawwell said: “Everyone at Celtic is deeply saddened by the loss of Tommy, a true Celtic giant and a man who gave the club so many years of his life in an illustrious football career.

“Firstly, I would like to send our sincere condolences to Tommy’s family, our thoughts and prayers are with them all. They will have every support from the club at this most difficult of times.

“Tommy was a Celtic great, one of football’s greats and I know he will be so sadly missed by everyone who knew him.
