Dublin - Stevie Chalmers, scorer of Celtic's winning goal in the 1967 European Cup final, has died at the age of 83, the club announced on Monday.
Chalmers is the second member of the Scottish giants' great "Lisbon Lions" side to die in the past week after captain Billy McNeill passed away aged 79.
"It is with great sadness that we announce the passing of Stevie Chalmers, our loving father and devoted husband to Sadie. The Celtic legend was surrounded by family when he sadly passed away early this morning," Celtic said in a statement.
Chalmers etched his name into Celtic folklore when he scored the decisive goal in a 2-1 victory over Inter Milan in Lisbon.
Like McNeill, Chalmers had been suffering from dementia in recent years.
"In recent times Stevie endured the toughest of battles, but just as he approached every game in a green-and-white jersey, he tackled his long-term illness with much bravery and dignity," added Celtic's statement.
Chalmers was one of Celtic's greatest-ever goalscorers, netting 231 times in 12 years for the club.
He won four league titles and three Scottish Cups as well as earning five caps for Scotland.
"This is a particularly devastating time for the Celtic family, with the passing of Stevie Chalmers coming so soon after his friend and former teammate, Billy McNeill," said Celtic chief executive Peter Lawwell.
"My condolences also go to the Lisbon Lions, already mourning the loss of their captain, and now grieving the death of another one of their own.
"Stevie Chalmers was a Celtic legend, and one of the greatest goalscorers this club has ever seen. Indeed, only three other legends in Jimmy McGrory, Henrik Larsson and Stevie's close friend, Bobby Lennox, have scored more goals.
"However, there is only one man who is able to lay claim to having scored the most important goal in Celtic’s 131-year history, and that man is Stevie Chalmers."
