Celtic great and member of the Lisbon Lions Tommy Gemmell has died.

The 73-year-old died after battling a long illness, Celtic announced on Thursday morning.

Gemmell featured more than 400 times for the Parkhead side and scored in their historic win over Inter Milan when Celtic became the first British club to win the European Cup in 1967.

Celtic said in a statement: "It is with great sadness that Celtic Football Club announces the sad passing of Lisbon Lion and Celtic great Tommy Gemmell after a long illness.

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

"Funeral details will be announced in due course."

The former full-back was a stalwart in Jock Stein's Celtic side, winning six league titles, as well as scoring in the 1970 European Cup final, which the Hoops lost to Feyenoord.

During his time at Parkhead, the defender made 418 appearances and scored 63 goals, including 31 of the 34 penalties he took during that period.

His haul of honours at Celtic included three Scottish Cups and four League Cups.

Celtic added in their statement: "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."

The Scottish FA paid tribute to Gemmell, who was capped 18 times by his country between 1966 and 1971.

He scored once, in an 8-0 victory against Cyprus, and also played in Scotland's famous 3-2 victory over England at Wembley in 1967.

SFA chief executive Stewart Regan said: "Scottish football has lost a true legend today with the passing of Tommy Gemmell, and we would like to extend our most sincere condolences to his family and friends.

"Tommy provided Scotland fans with many cherished memories over the course of his international career, none more so than when he helped the nation to a famous victory over the World Champions."

Scotland manager Gordon Strachan, who was in charge of Celtic from 2005 to 2009, said: "I am shocked and deeply saddened to learn of Tommy's passing and my thoughts go out to his family and loved ones.

"Tommy was a joy to watch on the pitch and, as a pioneer of the attacking full back role, was years ahead of his time.

"Throughout his career he earned the respect and admiration of his fellow professionals and fans alike, and his contributions to Scottish football cannot be overstated."

Gemmell later made almost 100 appearances for Dundee after a decade at Celtic.

He was captain when the club last lifted a major trophy, the Scottish League Cup in 1973.

A Dundee FC spokesperson said: "Everyone at Dundee Football Club was saddened to hear of the death of former player and manager Tommy Gemmell at the age of 73.

"The thoughts of everyone at Dens are with Tommy's family and friends at this sad time."
