Newly-promoted Ghana Premier League side B/A United continued their pre-season with a 2-0 over Elima Sharks on Monday.
Former Asante Kotoko midfielder Kwabena Dodzi cemented the victory in the second-half after Gideon Awuni had opened the scoring in the first-half.
Frimpong-Manso's side looked to have maintained their form from the Middle League Play-Offs as they displayed enough cohesion and understanding to outplay Sharks.
B/A United returned to the Ghanaian top-flight after spending close to eight seasons in the wilderness.
