Playing at home in Peter Mokaba Stadium, Bakgaga host the Western Cape side, who reached the last 16 stage of the Nedbank Cup competition by convincingly beating fellow amateur side Orbit College 3-1.
In the previous round, the Limpopo side beat Platinum Stars 1-0 in Rustenburg.
Caretaker coach Makhubedu, who has seen United in action at least twice, says he's got a clearer picture of what he will be up against tomorrow.
"They are tough those guys," Makhubedu tells snl24.com/kickoff.
"They normally play direct and rely on set - pieces because they have five big boys especially the two centre-backs, One of them is their captain, otherwise they are well organised.
"Mentally, players need to be strong [to get a victory against such teams], like when they play Pirates or Chiefs."
The match tomorrow is scheduled for 15h30.
