Glazer purchased the National Football League’s Buccaneers for $192 million in 1995 and helped turn the franchise into a Super Bowl Champion in 2003.
Glazer bought Manchester United for £790 million ($1.47 billion) in May 2005. The Red Devils have won five Premier League titles and the 2008 UEFA Champions League crown under his ownership.
In August 2012, the Glazer family successfully launched an initial public offering of Manchester United shares on the New York Stock Exchange, firming up his family’s control over the English soccer giant.
The Glazer family will continue to own both clubs and his sons, Joel and Avram, will retain their positions as co-chairmen of Manchester United.
“The thoughts of everyone at Manchester United are with his family tonight,” Manchester United said, according to the BBC.
Glazer leaves behind his wife, Linda, six children and 14 grandchildren.
