Bill Foulkes made his debut for the Red Devils against Liverpool in 1952, and has made 688 appearances for the club.
Only Ryan Giggs, Bobby Charlton, and Paul Scholes surpass Foulkes' appearances for United.
Foulkes survived the Munich air disaster in 1958 when he was only 26 along with Harry Gregg, Ken Morgans, Bobby Charlton, and several United legends. Bill spent his whole career playing at Old Trafford.
Ed Woodward, United's executive vice-chairman, sang the praises of Foulkes saying: "Bill was a giant character in the post-war history of Manchester United.
"He was a very gentle man, who I was privileged to meet on several occasions, including most memorably with his team-mates at the Champions League final in Moscow, 50 years later after his heroics in the Munich air crash.
"Bill's contribution over almost 700 games and nearly 20 years will never be forgotten. The thoughts of everyone at the club - directors, players, staff and fans - are with Bill's family."
Manchester United players also paid tribute to Foulkes. Former United captain Gary Neville tweeted saying that Foulkes is "a legend".
Rio Ferdinand also tweeted saying: "Sad to hear news of Bill Foulkes passing away. Great servant to the club. Thoughts are with his family".
Foulkes was a four-time league champion and an FA Cup winner. He also won the European Cup at Wembley with United, when the team beat Benfica 4-1 in 1968.
Foulkes left United in 1970 and went on to manage clubs in the US and Norway.
May God rest his soul in peace.
