United have won three out of three under Mourinho
Jose Mourinho and Pep Guardiola are set to battle it out for the Premier League Manager of the Month award.
The pair have enjoyed 100 percent starts at Manchester United and City respectively after arriving at their new clubs this summer.
At least one of the records will be brought to an end on September 10 though when the pair clash at Old Trafford in the first Manchester derby.
They have both been nominated for August's prize, along with Chelsea's Antonio Conte and Hull caretaker boss Mike Phelan.
