Ida Guehai was the heroine of the match as Logrono beat Tacon 1-0 in q Primera Iberdrola contest at Ciudad Deportiva Real Madrid on Sunday.
The Ivorian midfielder has stepped up to the occasion following the exit of Zambia's Barbra Banda earlier this month and has been making a huge impact, with two goals in last three ties for Logrono.
The Cote d'Ivoire international, who joined the Spanish top-flight outfit last summer from rivals Levante, scored the only goal of the contest to power her side to an away victory in Madrid.
After a goalless first half, Leticia Mendez set up Guehai to score in the 58th minute and ensured the visitors silenced the hosts.
