Dickie Best, father of United legend George, has passed away, aged 88.
He had been in hospital for the past four weeks and his family were with him when he died at the Ulster Hospital in Dundonald, Northern Ireland.
In a club statement, United expressed sadness at Dickie's passing.
"Dickie was hugely proud of his son George’s achievements at Manchester United and was always a welcome guest here at Old Trafford," read the statement.
"Everyone at the club was saddened to hear the news of Dickie’s sad passing and we send our condolences to the Best family, as do, we’re sure, United fans all around the world."
Reds' legend George Best died in 2005, but he is still fondly remembered at Old Trafford.
