The Red Devils head into the game looking to return to winning ways after the disappointment of their 1-0 loss to Southampton in the Premier League on Saturday afternoon.
Louis van Gaal’s men have struggled to find consistent form in recent weeks and have now only won two of their last 10 Premier League games.
Last weekend’s loss left United five points adrift of the top four heading into the final 15 games of the season.
However, Red Devils midfielder Herrera believes that the cup clash represents the perfect opportunity for United to find some form.
Herrera told MUTV: “FA Cup away games are always special, I don’t know why but they are. It’s a competition our fans love and we love it also.
“We play Derby who are near the top of the Championship and that means they will be very tough at home. I have watched some Championship games and they are very tough games. They are a good, strong team and it’s a big day for them playing Man United.
“I have very good memories of last season and the away games we played in the Cup. Our fans were fantastic in the away games and I could score in two games, so I’m looking forward to this next game.”
The 26-year-old Herrera has been a regular fixture in United’s first team so far this season.
The Spaniard has scored two goals and made two assists in 16 Premier League games for Van Gaal’s men.
