Seems like Cobreloa is having good period right now in Chilean Primera B league with five wins in last five games but Antofagasta belongs in Premier division so I see them as a favorites in this game. Antofagasta has two draws and two wins in their last four games and they are also playing solid currently. It will not be easy game for Antofagasta but I still think they have more to offer in this match so I take them as a winners today.
