Simon Moore insists the Blades must keep going, despite being gutted not to beat automatic promotion chasing Cardiff City on Easter Monday.
United looked on course for three valuable points following Leon Clarke's first-half opener, only for Anthony Pilkington to deny them in stoppage-time.
The recalled goalkeeper remarked: "The boys are gutted to be honest, it was probably one of the best performances of the season, but we've said that a few times this season.
"If you want to go up you need to see games like this out, but we remain in a very good position, following results elsewhere."
Moore added: "It's not hard to be positive with where we are though, we have six games to go and we're very much in the race for the play-offs.
"Once again we've been undone by that bit of quality in the last minute, just like against Bristol City and Villa."
