Hearts of Oak coach, Samuel Boadu has expressed disappointment despite his side's 2-0 victory over Algeria's JS Saoura.
The Phobians created several chances but only converted two as Hearts take a first leg advantage to Algiers next week.
Ibrahim Salifu and Isaac Agyenim Boateng scored at either side of half time to give Hearts victory.
"I saw their training at the McDan town Park. Tactically they are good and have better and quick movements. We knew they deal with long balls sometimes so we did all we could to stop their supplies," said coach Samuel Boadu after the game.
"I'm not happy with the scoreline because we created a lot of opportunities but is quiet unfortunate we couldn't take all those chances.
"We have learnt a lot from the WAC game heading into the second leg."
The Ghanaian champions have to avoid a three goal deficit defeat to progress to the group stages of the CAF Confederation Cup.
