Following the departure of British coach Peter Butler, Dikwena have moved swiftly to find a replacement ahead of the resumption of the Absa Premiership.
The Rustenburg-based outfit have turned to the former Maritzburg United mentor, who had been without a job since parting ways with the Team of Choice in March this year.
Stars took to their official Twitter to announce the arrival of their new tactician.
De Sa's first assignment will be to lift the team off the foot of the league table, after they failed to register a point under the departed Butler in their two games thus far.
Stars next visit SuperSport United at the Lucas Moripe Stadium on Tuesday evening, after this weekend's MTN8 semi-final action.
