The report says Elsa Cardoso was the decisive figure, scoring twice and giving Colonia a cutting edge from the start.
That matters in an opener. Teams can look sharp in patches in early-season games, but finishing usually decides whether control turns into a result. Colonia, by that account, were clinical enough to make their pressure count.
This was not only about one forward having a big day.
For a first outing, that is a useful sign. It indicates structure as well as individual quality, with chances apparently being created by more than one player and finished at key moments.
At the other end, Taylor Webb is reported to have made five saves to preserve the shutout.
The next test will be whether Colonia can carry that balance into their next fixture: enough creativity to keep scoring, and enough organisation to make the opener look like the start of a trend rather than a one-off.
