One of the main factors in this match is the high attitude of Estadio El Cobre de El Salvador, which is in the Atacama desert, and all teams have huge problems playing there. Cobresal at home is really strong with only 4 losses last season in 17 rounds, while this season they lost two times in 8 rounds. They arrive with enthusiasm, after winning their last four games, where they receive only one goal. Regarding Nublense, the squad led by Jaime Garcia finally won at home against Melipilla (who is relegation material), after 7 matches without a win. Away from home, they are really weak with only one win in 9 rounds and have 5 consecutive defeats at Estadio El Cobre de El Salvador.
