Mas-Ud Didi Dramani is now concerned about Asante Kotoko's ruthlessness at the other end after a frustrating 0-0 draw with Hearts of Oak on Sunday. The Glo Premier League champions dominated possession after a slow start at the Baba Yara Stadium but failed to convert clear-cut chances as they wasted the opportunity to join the top-four of the table. Kofi Nti Boakye, Michael Helegbe, Ben Acheampong, Michael Akuffu and Daniel Nii Adjei all missed opportunities for Kotoko although the visitors were fortunate to survive, courtesy a solid performance from goalkeeper Tetteh Lugard. The Porcupine Warriors are still the only side unbeaten after seven matches in the Premier League but they are nowhere near the scoring form that helped them to the title last season. "Matches involving Kotoko and Hearts of Oak has always been difficult. It was a very good and tactical game. We failed to take the opportunities we created," Didi Dramani, whose side sit sixth on the standings said. However the Kotoko coach is content with a point after the visitors who were reduced to ten men following the dismissal of Alhassan Ali with ten minutes of play remaining had an effort from a Laryea Kingston freekick cleared off the line in the first half. "But the result is good. I wanted a win against Hearts [of Oak] but in a league, getting a draw in a game like this is good." Asante Kotoko travel to the Tema Stadium to play Tema Youth on Sunday.
