Fulham boss Lawrie Sanchez has urged fans to be patient with his plans to overhaul the current squad.
"It won't happen from day one next season," he told Fulham's official magazine, Full Time.
"We are going to have major changes this summer with probably six, seven or eight players coming in. They will take time to gel.
"We need more than five weeks. To get where I was as Northern Ireland boss took three years.
"It was a gradual progression and along the way there were times when people questioned what we were doing.
"But as a manager and group of players we got through that and when I left we were top of the group.
"It will be a similar pattern for Fulham and I want to make people aware of that because there will be days when people question us.
"But I can guarantee that when we get to where I want to go, people will say 'Yes, this is not bad'."
