In this paper, we apply a three-stage-DEA model to the Spanish Professional Football League, which means separating the teams' economic behaviour into three components: operating efficiency—of the offence and defence — athletic or operating effectiveness, and social effectiveness. The results showed that the technical inefficiency of the defence is greater than that of the offence, both being caused by aspects linked to the poor management of players' abilities and by the football team's size. Teams showed a favourable evolution of their offensive and defense efficiency during the 2004/2005 season and to a lesser extent m the season before. The point system assigned by the professional football league regulations evaluates the teams athletic effectiveness, but we detected that the teams with the most experience perform athletically in a more effective manner. Their social effectiveness is strongly related to the level of play in itself and to factors linked to their PFL ranking: participation in international competitions for important football teams; or the struggle of minor football teams to stay in the first division.

The sporting performance of professional football teams has often been assessed considering their results in the major regular competition, namely the national league. Here, we show that evaluating league performance without controlling for extra games played in other competitions might produce misleading results. Using Data Envelopment Analysis, we assess the performance of Spanish professional football teams in the League controlling for the extra games played in the King's Cup, Champions League and UEFA Cup. Results show that assessing performance omitting extra games underestimates teams' true performance in the League, the more extra games played leading to greater bias. Consequently, the multioutput nature of football must be considered when assessing team performance. [ABSTRACT FROM AUTHOR]
