Jose Mourinho will be without experienced performers such as Ibrahimovic and Ashley Young for the crunch clash, but they will be with the travelling party.
Herrera considers that to be a good thing, with it important for everyone connected with the club to pull together in the pursuit of further success.
“I always say this is a team sport, we are a team,” the Spain international told reporters.
“The reason we have won two titles [Community Shield and EFL Cup] this season is because everyone has been there, working, helping. This final is for everyone.
“Of course 11 players will be on the pitch but everyone is ready to help and push for their team-mates. So, if we win it, it will be for everyone. Everyone has been part of this.
“Zlatan and Ash [Young] have very good experience. We need everyone.
“When you want to win a European trophy and you want to make a good season, it is not only on the pitch, you need help from the outside. Zlatan is here to help, Ash is also here to help. We are a team who is together. Everyone is important.”
Herrera has also reiterated that he expects Ibrahimovic to return to top level competition after recovering from the knee ligament damage which brought his 2016-17 campaign to a close.
It remains to be seen where the enigmatic Swede will turn out next, as his 12-month deal at Old Trafford comes to a close, but the 35-year-old is considered to still have plenty to offer.
“He is with us, he is supporting us,” Herrera added.
“I think he is very good. He is optimistic. He is 100 per cent sure he will be back because he cannot stop winning. He cannot stop scoring. For sure he will be back at the best.”
