The Buccaneers have been consistently linked with the no-nonsense defender, who led Wits to the 2016/17 Premier Soccer League (PSL) title.
"We need to beef up our defence. We need someone who will say, I will die for this team at the back. Hlatshwayo will be a perfect signing for Pirates," Sangweni was quoted as saying by IOL.
"They need someone who is stubborn at the back. You can't be soft if you are playing in that position. You don't have to listen what other people are saying. If you are playing that position you need to stay focused," he continued.
Pirates have signed nine players namely Asavela Mbekile, Ben Motshwari, Vincent Pule, Meshack Maphangule, Brilliant Khuzwayo, Kudakwashe Mahachi, Abel Mabaso, Paseka Mako and Linda Mntambo ahead of the new 2018/19 campaign.
According to the publication, the talks between Wits and Pirates are still ongoing as the Soweto giants look to beef up their defence. The 2016/17 PSL Defender of the Season committed his future to the Clever Boys by extending his stay to another three years in March 2018.
"Pirates need a stop nonsense type of the defender and Hlatshwayo can do that job. You must be prepared to fight for the jersey. At Pirates you have to think about the presence because you are as good as your last game," Sangweni added.
"We are expecting a lot from Pirates in the upcoming season. It is time for them to write they own history. Last season they showed glimpses of what they can offer. They must push more to attain silverware. Pirates can't be playing for the 2nd place all the time," Sangweni said.
Sangweni also disclosed that he spoke to his younger brother, Thamsanqa, who failed to live up to expectations last season after joining the Buccaneers from Chippa United in August, 2017. The central midfielder made only three league appearances under Pirates' Serbian tactician.
"I had a lengthy chat with my younger brother, Thami. I always tell him that Pirates is a big team. If you are given the chance, grab it with both hands. You must make use of every opportunity that comes your way. Your performance will speak for you at Pirates. It is also important not to pay attention to critics. You must always tell yourself that if I'm give an opportunity, I will always deliver. Whatever comes after that must be secondary," Sangweni explained.
"Competition is everywhere. He knows what he needs to do. They mustn't compare him to myself and he shouldn't succumb to that pressure because he will find himself in a spot of bother. He must be Thami. In football we will never be the same. He is Thami, I'm Siya and Lekgwathi is Lekgwathi," he concluded.
