Liverpool managing director Ian Ayre says they'll never return to the "dark days".
Ayre admits the "dark days" of the Tom Hicks and George Gillett era at Anfield taught him and the new owners the importance of respecting the club.
"It taught us the importance of sustainability and running the club properly. No one wants to go back to those dark days again," said Ayre.
"There was a lot to focus on: we had to improve the squad overall and that took investment at a time when we had little cash and a lot of debt.
"It was also important to put in the pieces to take the business of the club forward, because in a world of Financial Fair Play and sustainability they are the things which generate the revenue to buy the players."
