Notes: The table reports OLS estimates. Values between parentheses are robust stan-
dard errors clustered at the player level. Only observations associated with more than
71 minutes played and of players who are neither goalkeepers nor Austrian or Swiss are
included. Moreover, the sample includes only players who were active in both the 06/07
and the 07/08 season (before and after 21 Nov 2007), and with at least one strictly pos-
itive observation of the respective dependent variable in these two seasons.
