Great Olympics have confirmed the appointment of Yaw Preko until the end of the 2021/22 football season.
The former Ghana international will be serving as an assistant to the club's head coach Annor Walker.
He joins the Wonder club for the second time after his departure last season.
The former Ghana U-20 coach was recently fired as the head coach of Medeama SC after a poor run of results.
For the management of the Great Olympics, Preko's appointment is a boost for the technical team at a crucial time in the ongoing 2021/22 Ghana Premier League season.

The club on Monday defeated Real Tamale United 2-1 to move to second on the Ghana Premier League standings.
The capital-based outfit is just 9 points behind Asante Kotoko and aims to mount a chase for the title.
Preko will be expected to be in the dugout with Annor Walker when Great Olympics play Accra Lions in the matchday 19 games at the Accra Sports Stadium.
