Since 2004, Forbes has proposed a list of the most valuable soccer clubs. One year later, Transfermarkt began to estimate European soccer players’ value. This article estimate the determinants of firm values in European soccer over the period 2005-2013 incorporating player valuations, clubs’ operating income, and new ownership, three variables not included previously. The results of this study demonstrate that these variables are significant factors in club valuations. More generally, club assets including stadium age, club ownership type, supporter numbers and income, and past sports performances all have a significant impact.
