Fans in New Delhi were also treated to an appearance by ex-Reds defender David May, who made the trip to join in the celebrations with the Indian fans.
And the Treble-winner had high praise for the passion shown by the fans on the night. "It was like going back to the good old days, with the fans all chanting and singing," he said. "It was quite emotional at some points and it was great to be in that arena."
The celebrations for Sir Alex and his on-pitch farewell elicited strong emotions from May, who spent nine years under his guidance and admitted to having "a little tear in my eye".
May stressed the impact that an event such as #IAMUNITED can have on a local fanbase. "I think it’s great that United do this," he added. "It gives the ex-players a chance to give something back to the fans because some of them will never get to Old Trafford."
