Last term Zulu, who won the 2013/14 NFD Golden Boot with 16 goals for Black Leopards, was at Royal Eagles, while loan recruit Letlotlo spent the whole season nursing an injury at Kaizer Chiefs.
"You know this guy, I think he's done well but I don't know what happened to him," Mammila says to KickOff.com about Zulu, who also had stints at Chiefs and Chippa United.
"I think his injuries played a part in at least the last three years you know. So I think we just want to give him a chance you know. He was here for almost two weeks, there is something there we can work with, that's why he signed. Last season he was in the NFD at Royal Eagles but he was injured. You know sometimes people will always say this player is not good, and this player ... you know it just depends on a team. For an example, you know I will just mention [Leonardo] Castro. Castro as a player he can't do this, can't do this ... but he will come and take three points from your team. And why do you undermine a player but he comes and takes three points from your team? So you don't need all players that can play, sometimes you need goalpoachers. At the end of the day what counts is goals and points, not being skilful.
"With Letlotlo, he knows how to score goals. He is quick, he is young. He is from Limpopo so we are promoting more of our own because we can't keep on promoting you know foreign players while we got our own here. That's the criteria of Baroka, we promote our own South Africans huh? He is a versatile player, you really need those. He can score from any angle, he can come from wing, he is a number 10, can be a second striker."
