Nakumatt head coach Anthony Mwangi has termed the departure of striker Kepha Aswani as a massive set back to his side.
The Harambee Stars striker early this week, ditched Nakumatt FC for top-ranked Sofapaka who finished second behind leaders Gor Mahia last season.
The former AFC Leopards man was an integral figure for the shoppers last season, netting a total of 13 league goals.
"Aswani has been our most effective player on the pitch. He is a striker with experience, mature and who knows what he is doing. It will definitely affect us as a team considering he was one of our key players.
"Finding his replacement will not be easy, however, we have to do it, no two ways about it."
Aswani will have to fight for a starting berth with Ugandan Umaru Kasumba.
