Former England and United midfielder Ince takes Notts County - the club he now manages from England's third tier - to Bruce's Sunderland, who have soared to sixth in the Premier League.
"It's a tough game as they are flying," Ince, who also played for Inter Milan and Liverpool, told Reuters. "But we go up there with no fear and no pressure.
"We will enjoy the occasion and hope to do ourselves justice. We have seen over the years there are cup upsets, so why can't it be us?"
Ince joked that he only gravitated to him "because he liked a beer", but in all seriousness has the utmost respect for him.
That friendship even extended to Saturday's cup game. Ince called Bruce to see if County could use Sunderland's training facilities. Bruce not only agreed but said he would arrange lunch for them.
"That shows the quality of the man," Ince said. "When I went to United, we lived about 200 yards away from each other, we mixed together socially with our families and we see each other in Portugal every year when we go back to the Algarve."
"We are very close as he is someone who looked after me when I went to United. I get pleasure from seeing him do well and he deserves his success. I hope he will be the next England manager as he has respect from players."
"I have learned a lot after working with so many good people and I've discovered this job is about man management more than anything," Ince said.
"Fergie never took a coaching session until Thursday afternoon when we had 11 versus 11. He just sat upstairs with a coffee, looking out of the window at us and we'd all be too frightened to put a foot wrong.
"I had an illustrious career and I'm comfortable in life and have some great memories," Ince added. "I don't have to do this, but I want to do it. I want to show people that I can manage at the highest level."
His management career began in 2006 at little known Macclesfield, who were last in England's fourth tier. He overcame a 12-point deficit to stave off relegation.
