Former Celtic striker Frank McAvennie has spoken of his sadness over the death of 'Lisbon Lion' Tommy Gemmell.

The Parkhead club announced on Thursday morning that the ex-Hoops full-back, who scored in the 2-1 win over Inter Milan in the 1967 European Cup final in Lisbon, had died at the age of 73 after a long illness.

The news came following confirmation over the weekend that Billy McNeill - the Lions' captain and McAvennie's former manager - has dementia.

Boyhood Celtic fan McAvennie, 57, told Press Association Sport: "It is a shame.

"It has been a horrible week all round, really, with the news about Billy as well and now Tommy - two great men.

"I remember the Lions when they were playing. I was only a wee boy but I got to know them through the years when I played for Celtic and it was great.

"They are always about the place. I was on a couple of trips with Tommy and his knowledge of the game was incredible.

"He will be sadly missed at Celtic Park."

During a hugely successful career Gemmell also scored in the 1970 European Cup final in Milan but the Hoops were beaten 2-1 by Dutch side Feyenoord.

Former Celtic midfielder Murdo MacLeod described Gemmell as "one of the greats".

MacLeod, who also spent a spell as assistant manager at Parkhead, told BBC Scotland: "I know he had been struggling over the last few months. Just really sad news.

"He's obviously been one of the greats at Celtic Park to be part of the European Cup-winning side.

"A top player, one of the first defenders getting forward all the time. (It's) just so sad. We heard Billy McNeill's news over the last few days and now this. It's just very sad."

Former Celtic striker John Hartson wrote on Twitter: "Sad news hearing Tommy Gemmell has passed away.. Celtic great thoughts are with his family and close friends, RIP Tommy."

Celtic's Old Firm rivals Rangers said in a statement: "The club would like to send our sincere condolences to the family of Celtic legend Tommy Gemmell.

"He was one of the great Celtic and Scotland players and will be sadly missed.

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