The Tshwane giants face their crosstown rivals in the last 16 of the Telkom Knockout at Loftus Stadium in the midst of a glittering run of form.
The Brazilians have registered three consecutive league victories and Mphahlele says they will definitely guard against complacency in an effort to ensure further consistency.
“Obviously a cup game is a very difficult game,” said Mphahlele.
“It’s going to be a tough game, a tactical derby but we will give it everything we have to win the game.
“Tuks are a very good team and we will have to be alert on Saturday.”
The Tshwane sides have on recent occasions produced entertaining derbies and this one promises the same.
Mphahlele insists that he knows how Tuks coach Steve Barker normally approaches matches and he will bank on that come Saturday.
‘Rama’ was part of the Bafana squad that played in Shakes Mashaba’s AFCON qualifiers against Sudan and Nigeria and adds that he will put that experience into good use.
“Tuks are difficult to play against and I think it’s because of their determination,” said Mphahlele.
“They have nothing to lose. We are always expected to win and I don’t think this game will be any different.”
Kick-off is 5:30pm.
