Rantie's off the field disciplinary issues have been well documented, with the Parys-born man most recently having had his contract terminated by Cape Town City after playing a single game.
Mosimane reminisced about the dominant and free-scoring Rantie and spoke of his wish to get the 29-year-old back to the best. "He is powerful when he is fit and his condition looks okay.
I have good memories of Tokelo playing for Bafana and scoring against Cape Verde," he said. "I have good memories of Tokelo going against Nigeria and scoring two goals. Whether we are going to get that or not I don't know myself."
Rantie is eligible to make his debut when Downs take on SuperSport in MTN8 semifinal second leg tomorrow (Lucas Moripe Stadium, 7.30pm).
Mosimane said: "Yes he's available for selection, why not?"
