Coach Salim Babu is confident those who will be signed to replace them will bring in fresh ideas,
"We wanted to have new and youthful players who can help the team realize its ambitions next season," Babu told Goal.
"We wish the released players all the best in their future endeavours and at the same time thank them for their time with us. We will always be part of them, they are still like a family to us."
The Kisumu-based Powermen struggled to click in the top-tier last season despite having a good start. As a result, coach Paul Ogai was shown the door and Babu took his place.
The team has resumed training already and have recently sealed the services of Samuel Njau from Sony Sugar.
