He told The Sun: “You have to recover. The history of Manchester United is ‘another day’ and we will recover.
“We’ll come back. By January we’ll be OK. We usually get the show on the road in the second half of the season and that will have to be the case.
“We will react, no question about that.”
United current’s goal difference is plus 14 while City’s is currently plus 26 and Ferguson admits the ‘goal difference may count’ in the race for the title.
Ferguson added: “It’s the manner of the defeat.
“Goal difference may count. Last year it was in our favour, most years it is in our favour…this time, maybe not.”
