Liverpool boss Rodgers not jealous of Chelsea spending power
But he said: "Liverpool's owners are about building something and creating something that is going to be sustainable over a number of years.
"There's only two ways to do it in football.
"Either you invest a massive amount of money to get the top players or you be diligent in the transfer market and develop your own players.
"The second method obviously takes a lot longer than the first.
"Liverpool has a great history, but I can't afford to look in the rearview mirror. I must look forward."
