Amatsatsantsa and Bafana ba Style will meet in the Nedbank Cup last 32 Tshwane derby at Loftus Versfeld Stadium on Saturday night.
"It's clear how they play. They work hard off the ball trying to press and regain the ball.
"As soon as they have the ball they will look to keep the ball and suck us in to create space behind our defence. So for us, important game, tough game."
In the last meeting between the two sides, which was a league encounter, Sundowns walked away with all three points as they whipped their neighbours 2-1 at Lucas Moripe Stadium.
But Daniels says United are not going into this game with revenge on their mind.
"Well I won't say revenge," the reliable defender says.
"It's just important for us to put up a performance, a good team effort, a good fight to show that we can compete with the best in Africa.
"Once we do that I'm sure we have qualities that can win the game."
