The ex-Spurs captain says this revolution started from the boardroom - not the training ground.
Second in the table and five points behind Leicester City, Mauricio Pochettino's side find themselves with a chance at history as they bid to become the first Lilywhites team to win a league title since 1961.
Indeed, Pochettino has received plenty of praise for his contribution, as have the likes of young stars Dele Alli and Harry Kane, but Mabbutt says unequivocally that the man behind the scenes deserves a big doff of the cap for hiring the Argentine manager.
"The club as a whole is doing an excellent job. People ask me, 'Which jobs would you least like to have in football?' and there are two: one is a referee and the other is a chairman. Chairmen only got mentioned when they're doing badly. When things are going well, they never get mentioned," the former Spurs captain told ESPN..
"But we've actually got a board of directors who have worked really hard to put the club on a great footing. That's off the field, with the new stadium, and on the field by bringing together Mauricio and his backroom team which has got us to where we are now in the table.
"Things are looking very bright."
With Spurs also going strong in the Europa League, reaching the last 16 ahead of a tie with Borussia Dortmund, it is certainly exciting times for Pochettino and co, though the next few games could shape their season.
They travel to Signal Iduna Park on Thursday for the first leg with Dortmund, before going to bottom-of-the-league Aston Villa in a must-win game on Sunday.
Already five adrift of Leicester - who host out-of-sorts Newcastle on the Monday - Spurs must keep the pressure on Claudio Ranieri's side with a win. Defeat could potentially leave them eight points behind with eight to play, which would arguably be too big of an ask.
