Another popular tweet, gathering 13,000 retweets so far, came from the captain of arch-rivals Manchester City, Vincent Kompany, who wrote: "Sir Alex, one of the best managers of all time. After 26 years of success in the game, we all owe him a tribute."

Sir Alex Ferguson departs from Manchester United after serving as manager for 27 years. Since joining in November, 1986, he has guided the club to win 28 major trophies and 13 Premiership titles.
"The decision to retire is one that I have thought a great deal about and one that I have not taken lightly," Ferguson said. "It was important to me to leave an organisation in the strongest possible shape and I believe I have done so.
"To the fans, thank you. The support you have provided over the years has been truly humbling. It has been an honour and an enormous privilege to have had the opportunity to lead your club and I have treasured my time as manager of Manchester United."
Ferguson will now become a director at Manchester United Football Club. Everton' David Moyes is among the favourites to take over as manager.
