FSG chief Sam Kennedy says Liverpool remains a long-term proposition for them.
Kennedy is in charge of stadium development at FSG and commented on their plans at a recent Sportico summit.
He said: "We are in a new world, trying to figure out what is going to happen three of four years from now. If anybody can tell you they are lying.
"The good news is that we are in this for the long haul. Our investment came together in 2001 and in 2002 we closed (on a deal to purchase the Boston Red Sox). Since then we have added assets, franchises and real estate to the porfolio.
"We are inbuilt and invest for the long haul. Our time horizon is forever, especially when it comes to our real estate activity. We are taking a very long view and we don't have the typical expectations around quarterly returns or annual returns because we are in it for so long. It is a two-pronged strategy.
"Yes, we need a good economic idea on the real estate that we are developing but we also have to make sure that is additive to the fan experience to Fenway Park, Anfield and PPG (Pittsburgh Penguins' home arena)."
