But Liverpool's dominance in the 1970s and 80s has them two ahead on 18.
Fergie said: "We have won the FA Cup more times than anyone (11) and you get a certain pride in that.
"The same for Liverpool at this moment - they have won the title more times than anyone and they will be proud of that.
"But the chase is on, it will always be on, to be the No 1 in the country.
"I hope before I leave we can get to that position in terms of titles."
