The Ivory Coast striker notched an injury-time winner on Sunday as Swansea dumped the Red Devils out of the FA Cup.
That goal brought his total up to 13 this season since his £12million summer switch from Dutch side Vitesse Arnhem.
Bony, who also hit a brace in the defeat to Manchester City in the game before, is looking to be on the scoresheet once again on Saturday.
He told the Daily Star: "It was a dream finish for me and a dream result.
"It will give us a lot of confidence. We know it will be a different game from the cup but we will be ready.
"We will go there looking to win."
Bony has now scored five of his goals this season in the final 10 minutes of games.
He added: "I have scored quite a few goals this season in added time. It is important to keep your concentration right until the very end.
"You never know when chances might come, but when they do you have to score.
"I have told our wingers if they can get one cross to me, then I will score."
