The tactician has joined K'Ogalo, taking over from Carlos Manuel Vaz Pinto at the helm
Gor Mahia new coach Mark Harrison has promised fans and supporters entertainment as he starts his new job at the club.
The former Southampton goalkeeper is in the country to fill the space left by Carlos Manuel Vaz Pinto, who left the club in July after helping them win the FKF Shield Cup against AFC Leopards. Vaz Pinto's last league game was a 2-1 defeat to Tusker.
Sammy Omollo, who has been in charge since he was Vaz Pinto's assistant, is also expected to assume the same position under Harrison.
