The right-back said Ingwe had given him so much since he joined them from school almost three years ago.
The right-back has signed a two-year extension contract with the former champions and has now revealed reasons that convinced him to stay with Ingwe longer.
“I am delighted to announce that I have extended my stay at this great club that is AFC Leopards,” Mainge wrote on his Facebook page.
“It’s a club that has given me so much since I arrived in 2018 straight from school. I have worked with some fantastic coaches and players and I think this is the perfect environment for my development as a player.
Mainge has also made promises to fans who are eager to see the AFC Leopards lift the Premier League as their efforts have been unsuccessful for more than two decades.
“We have goals as a group and I believe that with hard work and dedication we will achieve them,” he added.
“For the fans who have supported me throughout my journey, I don’t take it for granted and the only way to show my appreciation is to give my best every time I go to represent the colors blue and White.
“God bless you. God bless the leopards.
Mainge was among the other two stars; Robinson Kamura and Jaffery Owiti who also signed two-year agreements. After signing the extension contract, Owiti, who joined AFC Leopards in 2017, made his goals known.
“I feel good to be part of the team again”, the attacker said. “The AFC Leopards have always been my home, which made the decision to renew my contract easier.
“My goal is to give my best and help the team win the league title and other cups.
“To the fans, thank you for your continued support and I hope this season you will support us even more despite your absence from the stadium. [due to Covid-19].
“We hope to put a smile on our fans with a title this season.”
The contract extension for the trio is the first business carried out by AFC Leopards in the mini-transfer window.
