Guardiola, who led City to the Premier League, FA Cup and Champions League trophies across the season, was on a three-man shortlist for the prestigious honour.
He beat off competition from Simone Inzaghi, who led Inter to the Ataturk Olympic Stadium showpiece final against City, as well as Luciano Spalletti, who won the Serie A title with Napoli.
In emerging victorious in Turkey on that memorable June evening, Guardiola became the first manager to win two European Trebles in the men’s game.
It helped him surpass the eight other bosses who have won one European men’s Treble, including Celtic’s Jock Stein, Stefan Kovacs of Ajax, Guus Hiddink with PSV, Sir Alex Ferguson with Manchester United, Jose Mourinho with Inter, Bayern Munich’s Jupp Heynckes, Luis Enrique of Barcelona and Hansi Flick of Bayern Munich.
The award was revealed at the Grimaldi Forum in Monaco this evening.
“Congratulations to Pep and his staff for winning this award, a deserved recognition for an incredible season,” said Director of Football Txiki Begiristain.
“To win three trophies was extraordinary and to lift the Champions League trophy for the first time was such a special moment.
“He is so focused on delivering success and sets high standards that keep us challenging for trophies every season.”
Everyone at City would like to send their congratulations to Pep on the award.
