He said: It's an honour to have been chosen by the Premier League as the Manager of the Season.
This award reflects the hard work and excellence of the people at the Club in all departments.
I am so proud to be manager of this group of players and to work alongside the brilliant coaches and support staff every day.
Winning four titles in a row is one of the proudest achievements of my career. This is the toughest league in the world and our competitors have played some incredible football.
When I arrived in England, I would never have thought that together we could win six Premier Leagues in seven years.
We have done something unbelievable and to celebrate that with our fans last Sunday was a day I will always remember."
Director of Football Txiki Begiristain added: Everyone at City is delighted for Pep and this latest recognition of his achievements.
As Pep is always quick to point out, our history making success is a team effort and would not be possible without the tireless work of our players, coaches and backroom staff.
However, Pep's inspirational leadership and drive to succeed has made us a beautiful team to watch and seen us once again come out on top in the toughest league in the world.
He has taken the Club to the summit of the game and everyone connected with Manchester City should be very proud that he represents us."
Arsenal's Mikel Arteta, Aston Villa's Unai Emery, Bournemouth's Andoni Iraola and Liverpool's Jurgen Klopp were also shortlisted for this year's award.
