The Catalan led City to a flawless four wins from four league games, a run that saw his side score a remarkable 17 goals without conceding.
The run extended Manchester City's winning run to five EPL matches and are top of Premier League on goal difference ahead of city rivals Manchester United.
A week later, Sergio Aguero scored a hat-trick in the 6-0 annihilation of Watford at Vicarage Road, while Raheem Sterling was the standout star with a brace in the 5-0 destruction of Crystal Palace that followed exactly another week down the line.
It's been a superb start to the new campaign for City. In September alone, they won seven straight games, scoring 25 and conceding just once.
Everyone at City would like to congratulate Pep and the rest of his staff on a well-deserved award.
