Head coach of Hearts of Oak, David Ocloo has promised to work hard in order to turn things around for the club with two games to end the Ghana Premier League season.
The Phobians fell behind in stoppage time of the first half to a Kofi Kordzi drive into the bottom corner which beat Atta in post.
The Royals were resolute and held on that solitary goal to ensure Hearts of Oak suffered a third consecutive defeat.
Hearts of Oak have been in dismal form, losing four of their last five games in the league.
But Ocloo says they will work in order to turn things around in the last two games of the season.
“We have two matches to end the season, we will go back again and try and push more at the training grounds and see if we can turn things around in the next two games” he said after the game.
Hearts of Oak are 8th on the league standings with 45 points and they will host RTU at home for their next match.
