Rumours doing the rounds is that AmaTuks defender Buhle Mkhwanazi is a target for cross-town rivals SuperSport, who are desperate to secure the services of a solid centre-back.
Mkhwanazi was part of Bafana Bafana's squad for the African Nations Championship, and has already impressed some of the big clubs on the local front.
United have struggled to keep clean-sheets this season, and with only Bevan Fransman and Edwin Gyimah recognised central defenders, Mkhwanazi could add plenty to the Matsatsantsa ranks.
Meanwhile, SuperSport coach Cavin Johnson will continue to look for players from his former employers Platinum Stars, with a move for skipper Vuyo Mere looking the likely pursuit. Johnson and Mere teamed-up well in Rustenburg and with two Cup victories already under his belt this season, Mere would add spark and tenacity at the back for Johnson's outfit.
Having already lost the likes of George Maluleka, Mogogi Gabonamong and Kurt Lentjies, United will have to splash the cash and bring in some reinforcements, but another threat of a possible exit looks large, in the form of Sameehg Doutie.
Johnson will have plenty of work to do in convincing Doutie to stay in Pretoria, after the fiery winger is said to be in advanced talks with Bidvest Wits, in a deal that would reunite Doutie with former coach Gavin Hunt.
Hunt is a long-time admirer of Doutie's and with a lack of creativity within his ranks, the former SuperSport coach looks set to turn to Doutie to make him a vital part of the way forward for the Clever Boys.
Sundowns have been uncharacteristically quiet so far this window, with no signings to announce as the window runs down toward its conclusion.
The Brazilians are, however, monitoring Nigerian youngster Ejike Uzoenyi, who is one of the stand-out performers at Chan.
Ejike has been in fine form, netting three goals in his four outings at Chan so far.
With his experience and class, Sundowns could be the ideal fit, and with a purse to match his salary demands, coach Pitso Mosimane will be licking his lips in anticipation at signing such an established young attacker to add to his ranks.
The notable departure from Chloorkop this window has been the news that Katlego Mphela will leave Sundowns for Kaizer Chiefs at the end of the season, but other exits look unlikely at this stage.
Wayne Sandilands is the only player who seems to be gunning for a move away from Mosimane's side, having been sidelined and replaced by Kennedy Mweene in goal.
Sandilands still has national ambitions and will need to move to a club where regular game time will be guaranteed, with his time at Sundowns looking like it could be coming to an end.
Free State Stars look the early favourites for his signature, but Ajax Cape Town have now emerged as a possible contender to Stars, but Sandilands is said to be eyeing a move oversees, with Belgium his preferred option.
