The 25 year old is presently ninth on the list, with 156 - 93 behind Charlton, who amassed an impressive 247 before his 17-year stint with the club ended in 1973.
Ferguson can see no reason why the gap cannot be bridged.
"I do (think he can eclipse that feat)," Ferguson told Inside United.
"He is only 25 years of age, so you'd think he has at least another five years in him at the very top level.
"And if he looks after himself like Ryan Giggs has done, he could play well into his 30s.
"The opportunity is there and time is on his side. He's raced out of the blocks already this season and I hope he could get up to around the 30 mark."
