Manchester United scored 10 goals in victories over Newcastle, Stoke and Chelsea - earning Ferguson the award on the 26th anniversary of his appointment.
The Scot has now won 27 monthly honours since the Premier League was inaugurated, and he told Sky Sports News: "I'm pleased with our attacking play, that's been a feature of our game.
"We've had an issue about defending, but in Saturday's win against Arsenal we were back to what I expect of Manchester United defenders."
Chelsea's attacking midfielder Mata, meanwhile, took a first individual award in England after scoring three league goals during October.
The Spaniard is thriving alongside Oscar and Eden Hazard, and he said: "I'm really enjoying it, they're players who like to play with the ball, to assist and who have good movement - more or less like me."
