Asante Kotoko squandered a second-half penalty, before slumping to a 1-0 defeat to defending champions WA All Stars at the Malik Jabir park to begin the post-Zdravko Lugarusic era.
Kweku Asuandzie Baffoe scored 10 minutes to half-time and goalkeeper Richard Ofori made some key saves to help the Northern Blues hold on for victory and condemn kotoko to their fifth consecutive league game without a win.
Abeiku Ainoonson missed the penalty in the 58th minute, when his tame shot was blocked by the experience Richard Ofori.
The Porcupine Warriors dominated play in the 30 minutes but failed to make the most of possession before the home side opened the scoring minutes after finding their feet in the contest. Asuandzie Baffoe capitalised on poor defending and bundled his effort home.
In the second half, Kotoko doubled their efforts and it almost paid off. Defender Abeiku Ainoonson should have converted from penalty spot to salvage point for the troubled side. They wasted two glorious chances thereafter.
