The three-time Premier Soccer League winners shut their door on top-flight football last week as they sold their status to Siwelele Football Club.
But with a thriving development set-up, Matthews explained they will continue to run their own academy for now.
He said in the Citizen: "This is a moment of evolution, not disruption. Our commitment to excellence in youth development is as strong as ever.
"I want to reassure you that our academy is secure, stable and going nowhere. Nothing fundamental will change before at least 2027."
Matthews explained that the coaching and staff will stay the same but all existing academy player contracts will be transferred to Siwelele.
"I will continue to lead the academy, as I have proudly done for the past 26 years.
"Our mission remains unwavering and that's to develop world-class talent like Ronwen Williams, Teboho Mokoena and recently graduates like Shandre Campbell, Neo Rapoo and Ime Okon.
"We are super excited to announce that a new top international club partner will be joining us on this journey, with further information to be shared soon," he continued.
