Liverpool's valuation has risen by as much as £535m over the past two years according to analysts from US sports business website Sportico.
Reds owners Fenway Sports Group are currently in the process of sourcing fresh investment into the club through a partial sale, although they would be willing to listen to offers of a full sale. The latter is understood to not be principal owner John W. Henry's preference at this time.
The valuation of the club is something that has been a hot topic, with the Reds, acquired in 2010 by FSG for just over £300m, in play with a valuation north of $4bn. Sources with knowledge of the deal in the US told the ECHO last month that only offers above and beyond $4bn would spark any kind of high level talks.
