Hearts of Oak suffered a surprise defeat to Berekum in their opening game of the 2019/20 Ghana Premier League season on Sunday.
The visitors shocked the Phobians at their back yard with Attuquaye's deflected shot effort in the 34th minute of the game at the Accra Sports stadium.
Hearts made an impressive start to the game by forcing newly signed goalkeeper Dan Lad Ibrahim into making some crucial saves.
Despite the numerous chances created by the home side, Chelsea managed to hold on before opening the scoring some few minutes later.
Ten minutes after the recess, the Phobains came close to finding the equaliser following a thunderous shot from Raddy Ovouka, but the effort was saved by Dan Lad Ibrahim.
Under-pressure Hearts coach Kim Grant made his first change this season by bringing on Kofi Kordzi for Aminu Alhassan, as his side chased the game.
Michelle Sarpong replaced Bernard Arthur with 20 minutes left and moments later Solomon Oblitey was brought on for Kofi Owusu for the Blues.
With ten minutes left Kofi Kordzi effort from outside the box graced the post to deny the Phobians an equalizer.
