Sergio Aguero's last-gasp winner against Queens Park Rangers saw City snatch the title from under the noses of United, who briefly thought they'd retained their crown by beating Sunderland on the final day of the season.
"When you look back on last season, it tells you the story of Manchester United," Ferguson said in his two-minute message to season-ticket holders.
"There is no club in the world who can create the drama that we created last year.
"Okay, it didn't work out our way this time but when you go back through the years and the number of times we have scored last minute goals it just added to the excitement and drama of Manchester United.
"It will always be there because that is the kind of club we are.
"When you are buying your season ticket you are guaranteed:
1) A possible heart attack.
2) Incredible excitement in the last minute of games.
3) Hope that we win the championship back."
United look set to miss out on one transfer target already this summer after Eden Hazard opted to join Champions League winners Chelsea, although there has been no official confirmation from the club.
However, the Red Devils are hoping to sign Japanese midfielder Shinji Kagawa from German champions Borussia Dortmund.
