Barry Robson insists the Blades remain very much in contention for automatic promotion, despite Tuesday's 2-2 draw with Brentford.
The Blades looked to be on course to keep their destiny in their own hands with victory against the Bees, but Bradley Wright-Phillips netted a late equaliser to leave United five points behind second placed Bournemouth with three games remaining.
Robson says the fight goes on: "That performance showed everyone just how committed the players are to winning promotion.
"We have proved in the last two matches we are capable of getting results and in the last week of the season it will be all to play for."
Commenting further on what Chris Morgan described as a 'crazy game of football' at Bramall Lane on Tuesday night, Robson added:
"We were gutted not to win the game and with everything that happened we still can't believe we didn't get all three points.
"Brentford gave it a real go as you would expect and they never gave in, but we should have kept the ball better in the latter stages.
"Perhaps the madness of the occasion got to us a little, but we showed massive character in the second-half.
"We had enough chances regardless of everything that went off to win the game, but we must stay positive."
