The blank scores are the useful starting point: CD Universidad Católica scored no goal in 2 of five recorded completed games; Liga Dep Universitaria Quito did so in 0. CD Universidad Católica most recently played Independiente del Valle (0-0) and previously Barcelona SC(ECU) (1-1); Liga Dep Universitaria Quito most recently played Macara (1-2) and previously Sociedad Deportiva Aucas (1-1). The two short sequences contain different opponents and cannot rank the teams by strength. I would follow how CD Universidad Católica responds if its first attack stalls. A zero-goal result does not explain why chances failed; lineups and chance quality are still unconfirmed, so this is an observation for the match rather than a winner prediction.
