Yaw Preko will be in the dugout on Friday when Great Olympics take on Inter Allies on Friday.
The former Hearts of Oak boss replaced Annor Walker who has left the club due to illness as Footballghana.com confirmed earlier.
Olympics have been on a good run in the ongoing season until Annor Walker was hit by illness.
The club suffered back to back defeat against Aduana Stars and Ashgold with Annor Walker in the dugout.
However, Yaw Preko will be hoping to get his first win on Friday when Inter Allies host them at the Accra Sports Stadium in the matchday 9 fixtures.
Olympics are currently occupying the 7th position on the league log with 11 points.
