Luton boss Rob Edwards concedes their clash with Sheffield United is massive for both clubs.
The Hatters host United later on Saturday.
Edwards said: "The goal is to try to win the game, and we will try to do it as well as we can.
"We go into the match with the expectation that it will be difficult and a tough physical match. Both teams are fighting for their lives so it will be close.
"I think we have been good and entertaining to watch. We have done well and I hope it will be a good game for the fans tomorrow (Saturday)."
