I like to compare Liverpool to the Boston Red Sox, I think you can't change the name of the stadium even if you build a new one...if the BoSox get a new stadium it WILL be named "New Fenway" and eventually be "Fenway Park" again and yes there will be a Green Monster in Left Field just like there is right now and the dimensions of the field won't change at all.

They'll eventually work it out to where it's still Anfield even if a company has to pay to keep the name the same (which would in turn win over a bunch of fans).
