Fulham owner Shahid Khan is prepared to invest heavily this summer to restore the club to the Premier League at the first attempt.
The Cottagers' 13-season stay in the top flight ended this season with a 19th-placed finish after using three managers.
The American billionaire said in the Evening Standard: "This is not about balancing the books.
"I am committed and we are going to do whatever to get them back to the Premier League. It (relegation) is not what we wanted, but it is reality. What we have to do is build it for the long haul.
"We are going to do whatever it takes to put the best team on the field. I have talked to Felix and what we want to do is what is in the best interest of the team."
