A dad-of-three who went to bed to watch Match of the Day had a brain hemorrhage in his sleep and never woke up.
Chris Munday's wife Kellie heard a 'loud gasp' and a 'funny noise' coming from his room, and then found him unconscious in bed.
She called an ambulance and he was taken to hospital, but died a while later.
The 46-year-old Manchester United fan had never had any problems and was described as "healthy" by his loved ones.
His family and friends have now started a fundraising campaign to help his wife and three children, Lucia, 15, Francesca, 13 and Giovanni, eight, pay for funeral and living costs.

Chris' friend Derek Duguid, 43, from Glasgow, told the Manchester Evening News: "Doctors said they will probably never know what exactly happened or why it happened.
"They said anyone could have them and be affected by these bleeds.
"This would have happened within a second."
His kidneys and heart valves were donated.
Paying tribute to his friend, Derek continued: "He was a funny, big character. He was always there for his family. He was happy. His children all adored him, he was his son's hero.
