Ferguson did not enjoy his last visit to Fulham, when United lost 2-0 in March
Manchester United manager Sir Alex Ferguson wants new rules to improve the size of Premier League dressing rooms.
"Everton's are so narrow it is unbelievable," Ferguson told Inside United magazine.
"Portsmouth's away dressing room is not great and the one at Craven Cottage is smaller than my office.
"Fulham is one of my favourite grounds but when you have 18 players stripping down, plus coaches, physios and kit men, it is ridiculous really."
Ferguson had an unhappy time when United last visited Craven Cottage, with Fulham beating his side 2-0 on 21 March, but that was their first defeat there since 1964.
Now the United boss has claimed Fulham's facilities are too cramped, adding: "With all the money in the Premier League, some grounds should be better.

"There should be a minimum standard of size of dressing room, especially now you have more players on your bench and an increased staff.
"You have requirements for stadiums to be eligible for certain divisions, so the quality of the dressing room should be part of that."
The facilities at United's ground Old Trafford get Ferguson's approval, and he has also has no complaints about those at Arsenal's Emirates Stadium - where his side will play the second leg of their Champions League semi-final next week.
He explained: "There is plenty of room in the dressing rooms at Old Trafford and, of the away grounds, Arsenal's are the best by far."
The BBC was unable to contact Everton or Fulham for their response to Ferguson's claims.
