Celtic and Scotland football legend Danny McGrain has been diagnosed with Alzheimer's disease, the club confirmed on Tuesday. Celtic has been in close contact with McGrain and his family since the diagnosis.

McGrain, a true icon of Scottish football, is widely regarded as one of the greatest full-backs of his generation. He played 663 competitive matches for Celtic between 1970 and 1987, securing seven league titles, five Scottish Cups, and two League Cups during his tenure. He also earned 62 caps for Scotland and was considered by many to be the best right-back in world football during his prime.

The 76-year-old remains a beloved figure at Celtic, not only for his playing career but also for his extensive charity work and role as a club ambassador. McGrain's wife, Laraine, stated that the diagnosis was received some time ago and that the family felt it was the right time to be open about his condition.

"Danny has always loved helping supporters - whether through hospital visits, assisting fans with charity events, or sending messages of support," Laraine McGrain said. "As time has gone on, that has become more difficult for Danny, so we wanted to explain his situation with honesty, and with the care and respect the Celtic Family has always shown us."

A statement from Celtic Football Club emphasized that McGrain is managing the diagnosis privately with his family. Despite the challenges, the club noted that McGrain remains in good spirits, enjoys time with loved ones, follows the game, and stays connected to the club.

"Regarded as Scotland’s greatest-ever full-back, he was widely considered by football experts, journalists, and peers to be the finest right-back in world football during the 1970s," the club statement read. "Danny has remained a constant presence at Celtic over the years through a range of coaching roles, supporting our Youth Development Programme via Celtic Pools, and hosting hospitality at Celtic Park."

Michael Nicholson, Celtic's chief executive, added, "When we talk about Celtic legends, Danny will always be right at the top of that list. He is a true great of the game, and we are deeply grateful for everything he has given to Celtic and to the people around him."

Nicholson concluded, "Danny has meant so much to so many supporters, and at this time we fully respect the openness shown by Danny’s family. The whole club will ensure Danny and his family receive our full support, care, and kindness throughout what lies ahead."
