As earlier reported by KickOff.com, Komphela has returned to the fore after penning a two-year deal, with an option of a further year, with Phunya Sele Sele, who recently parted ways with coach Veselin Jelusic.
The club have since confirmed the appointment on their official website, with chairman Max Tshabalala further explaining what led them to the former junior national team mentor.
“Our strategy was to get a reputable local coach with immense pedigree who can take us to greater heights, and in Steve we've found an appropriate candidate,” said Tshabalala.
“Last season was complicated and we failed to achieve our goals. However, we have now acquired the services of someone passionate, hungry for success and willing to bring back the excitement synonymous with Celtic supporters.
"He has the judgment, knowledge and experience. He promotes the youth and has an exceptional eye for raw talent and that is exactly what we need as a team.”
Komphela was on the recieving end of some harsh criticism from the Amakhosi faithful, who ultimately pressured him into quitting the club after three trophyless seasons in April.
The tactician, who will turn 51 on July 1, has previously enjoyed spells at Maritzburg United and Free State Stars - both of whom he achieved top-eight berths with in recent years.
Siwelele will now have similar expectations of the former Bafana Bafana defender, after they ended in the bottom half of the table in the last three seasons.
