Ahead of the new season, Fiacre Ntwari was signed with Amakhosi, hoping he can bring much needed stability.
However, he struggled to settle and was initially replaced by Petersen, before Bvuma once again outmuscled them to the starting berth.
Since taking over, he has played 16 league matches and conceded 17 times, keeping just five clean sheets in the process.
Retired goalkeeper Joseph Setlhodi, who is one of the club's founding members, does not believe Bvuma has the qualities to help the Soweto giants get to their best.
