Former Celtic captain Billy McNeill has died at the age of 79, his family have announced.

McNeill, who played for Celtic his whole career, was captain of the famous 'Lisbon Lions' side who won the European Cup in 1967 and he also went on to manage the club.

A statement from his children on the Celtic website read: "It is with great sadness that we announce the death of our father Billy McNeill.

"He passed away late last night (Monday, April 22) surrounded by his family and loved ones. He suffered from dementia for a number of years and fought bravely to the end, showing the strength and fortitude he always has done throughout his life."

McNeill joined Celtic in 1957 from junior side Blantyre Victoria and holds the club record for most appearances with 822 over 18 seasons. The defender also won 29 caps for Scotland.

He had two spells as Celtic manager spanning nearly 10 years in total and won 31 trophies across his long association with the club.

The statement continued: "While this is a very sad time for all the family and we know our privacy will be respected, our father always made time for the supporters so please tell his stories, sing his songs and help us celebrate his life."

Football pundit and former Celtic striker Chris Sutton tweeted: "Such heartbreaking news. Billy McNeill was an inspirational leader, a legend and a lion. Thoughts go out to his family and the Celtic family."

Former Celtic striker Frank McGarvey, who McNeill signed from Liverpool in 1980, told Press Association Sport: "It is a very very sad day.

"He was loved by all the players and you don't hear that about all managers.

"He was the captain of the first team to win the European Cup. As a manager, he was a great manager.

"He won a lot of trophies with Celtic on and off the pitch but not only that, he was a great person, a fantastic man. He would do anything to help you.

"He will be sadly missed."

Aberdeen, who McNeil managed in the 1970s, tweeted: "Our thoughts and prayers are with the family and friends of our former manager, Billy McNeill who has passed away at the age of 79."

McNeill was the captain of Jock Stein's all-conquering Celtic side of the late 1960s and early 70s, winning nine league titles in a row, seven Scottish Cups and six League Cups.

He retired in 1975 after winning his final trophy, the Scottish Cup, and retained a strong association with the club throughout the rest of his life, becoming an ambassador in 2009.

Six years later a statue of McNeill holding aloft the European Cup was erected outside Celtic Park.

Celtic chief executive Peter Lawwell paid tribute on the club website, saying: "This is the saddest of days for the Celtic family, and also for the wider football world.

"We mourn Billy McNeill's passing and we send our thoughts and prayers to his family and friends, while we also give thanks for Billy's life and the incredible joy he brought to so many people as a Celtic player, a Celtic manager and a great Celtic man."

McNeil's former team-mate Jim Craig tweeted: "Heartbroken over the passing of my great friend and captain Billy McNeill. A huge blow for the Celtic family but a devastating loss for Liz, Susan Libby Carol, Paula and Martyn.

Manchester City tweeted: "We are sad to learn of the passing of Billy McNeill who managed the Club between 1983-86. Everyone at Manchester City would like to send our sincere condolences to Billy's family. "

In a statement posted on the club's website, Celtic manager Neil Lennon said: "This is such sad news and I want to send thoughts and prayers to Liz and all the family from myself and all the backroom staff here at the club.

"When you think of Celtic and our incredible history, Billy McNeill is always one of the first names that comes to mind. He was our greatest ever captain and one of our greatest ever players, and along with his team-mates, achieved historic things for Celtic in the 1960s and '70s.

"I love Billy's statue, which is the first thing you see whenever you walk up The Celtic Way. It's the perfect image of him, holding aloft the European Cup, and it will remind future generations of supporters of what a great Celtic man he was."

Lennon added: "As a Celtic supporter, to get the chance to play for the club, captain the team and finally to become manager is something that dreams are made of. The fact that I've achieved all three is something that I really appreciate, and the fact that I'm following in the footsteps of a legend like Billy McNeill makes me truly lucky.

"Billy was a brilliant Celtic player, and a great manager, and as a player and a fan myself, it was always a great experience whenever I would meet him and chat to him. He was so positive and supportive, and always wanted all of us to do well because, if we did, it meant that Celtic were doing well and, for Billy, that was everything.

"This was his club, and he devoted his professional life to Celtic. In turn, he received the gratitude, admiration and love of every Celtic supporter.

"This is more than a club, with Celtic known throughout the world, and it is because of people like Billy McNeill that this is the case. He was a giant of the game, a true Celtic legend and someone that we will all miss."

Celtic captain Scott Brown posted an image of McNeill on Instagram and wrote: "Captain leader legend. Rest in peace."

Former Rangers captain John Greig was McNeill's rival during their playing days but also a friend.

He told Press Association Sport: "It's very sad news. I realise Billy has been unwell for quite a while and I've lost a very good friend today.

"We have been close for many, many years. Although we were big opponents on the field we had a mutual respect for each other off it.

"As Old Firm captains, we were asked to do a lot of public engagements together. We were even given doctorates from the University of Glasgow on the same day in 2008.

"Apart from being a great football player and a great captain for a great Celtic side, he was also a great guy, a real gentleman and I'll miss him."
