This article assesses the effects of home-field advantage and relative quality over the in-game decisions and performance of the teams playing in the Colombian First Division of association football. The Correia-Machado model is modified in order to explicitly include home-field advantage joint with relative quality of the teams as determinants of their performance. With a database for 2009 tournaments information, we find that different specifications for the quality of teams is not a determinant of offensive play decisions taken, unlike the field where the match is held which actually does it.
