Velez Sarsfield-Universidad Catolica Under 2.5 [-116]
Velez Sarsfield is about through to the QFs after beating Catolica 2-0 in the 1st leg on the road. As such, you'd expect them to take few chances with that lead in place. Catolica may be ready to throw in the towel as they have a league match to consider this weekend and could not break through at home. Siding with the under here in what I think might be a dull affair so long as the home side keep it clean.
