The Indomitable Lioness star outshined her compatriot as her side maintained their winning run in Tuesday’s Russian Superliga encounter
Onguene was handed her 10th season start by Maksim Zinovjev’s team, having got a goal in CSKA’s 3-0 win over Yenisey in their last league outing two weeks ago before the international break.
Before Tuesday’s fixture, the Cameroonian striker had six goals in nine matches this term, including the last registered goal in their recent away victory on September 12.
While compatriot Ekogo was in action for 59 minutes on her sixth outing this season but could not rescue Zenit from their second defeat on the bounce before she was replaced by Tatiana Morina.
Up next, CSKA will shift attention to their European qualifying round campaign before returning to face Chertanovo on October 31.
On their part, sixth-placed Zenit will aim to bounce back to winning ways when they welcome Zvezda Perm on October 11.
