Bolivar x Racing
Bolivar needs to win by 2 goals, Racing needs to avoid losing by 2 goals. I like this bet for several resaons. Racing will miss their top 2 strikers, Milito, and Bou. Lisandro Lopez will be the lone striker. He could be considered a regular striker, because he played well this season, but he is not used as playing as a lone striker.
Racing will change their system, because they want to defend. They will play 4-4-1-1, which i think is a horrible idea, because they are one of the most overish teams in Argentina, and have never played this system until now.
