Colombia vs Ecuador prediction (Over/Under)

In the 6'th round of South Ameria- Wolrd Cup qualifincation, Ecuador, the leader, will face Colombia, from 7'th place. Ecuador played amazing until now winning against Uruguay as the guest and against Argentina as the visitors. I think this is a big thing for them. The thing is that Colombia won the last 4 head-to-head games against Ecuador and they could have some issues here. Look to be sure an under 3.5 goals bet because it will be an intense game and both team will accord major attention to the defense.
