Blades boss Nigel Adkins is demanding his players remain focused on their own jobs, rather than worrying about results elsewhere.
United head to Roots Hall for Wednesday Sky clash against Southend nine points adrift of the final play-off spot, with eight matches remaining, but the Gaffer is remaining upbeat and persistent.
Ahead of departing to Essex, Adkins remarked: "We are in good spirits ahead of the trip and there is a real confidence within the group.
"We are looking forward to the game, it's the next challenge, the next opportunity to get three points and that's what we are concentrating on.
"The league table will take care of itself if we win enough games of football, so we aren't looking at it at the moment, we are just focusing on getting the performance right on Wednesday night and hopefully if we do we give ourselves an opportunity to win the game.
"We played well against Crewe, our first-half performance was exceptional and the grit and resilience we showed having been pegged back to win the game was very pleasing.
"There is a gap we are well aware of that but all we can do is our bit during the run-in, teams will get edgy, there will be ups and downs throughout the coming weeks, but simply we have to win a number of matches."
On the challenge the Shrimpers will pose his side, the Blades boss added: "Southend change their formation around a lot, they can be very direct and that will mean be have to defend balls into the box, but I want us to impose ourselves on the game.
"Phil Brown ruled Southend out of the play-off race after defeat at Rochdale, but perhaps he was just taking the pressure off his players."
