United have not been doing well since being beaten by Bidvest Wits in the Absa Premiership at Super Stadium on February 24, winning only one match against Mpumalanga Black Aces in the Telkom Knockout Cup last month.
Matsatsantsa are now faced with more difficult task to overcome on-form Kaizer Chiefs in the Nedbank Cup Last-32 match on Sunday.
Speaking to KickOff.com ahead of the epic battle against Amakhosi, United's Ugandan international goalkeeper Denis Onyango conceded that their opponent's current form was a big threat for them but said they were ready for the challenge.
"They are on form and after winning the Cup Final against Ajax Cape Town last weekend and will definitely will be looking forward to continuing with the momentum.
"We also have been hard at training for the past two weeks and the guys are fired up for the game against Chiefs. We beat them twice in the League this season and they will obviously be looking to get one past us this time.
"We owe it to our supporters because we have not won a Cup Final in recent times and hopefully we will make them happy come Sunday."
Onyango also welcomed the return of Daine Klate back from the Bafana Bafana camp in Brazil.
"He is one of our best players and after his trip to Brazil his fitness level is very high. His return is big boost for us ahead of the game."
