The 20-year-old, who made his PSL debut in December last season, currently provides cover to Bafana Bafana international Ronwen Williams at Matsatsantsa.
"He is happy to stay with SuperSport United," Msibi's manager Mandla Mthembu tells KickOff.com.
"He is competing with a national team goalkeeper but he is ready to continue working hard."
Mthembu adds: "Also he has been doing well with his studies at TUT. It's all about time-management and it's good that the youngster has realised that there is also life after football."
Msibi is in his first year at the Tshwane University of Technology, studying sport management.
