Simon Moore has admitted Sheffield United must be relentless in order to win promotion.
Chris Wilder’s side are fourth in the League One table after taking 17 points from their last seven games.
But Moore, the former Cardiff City goalkeeper, admitted even a momentary loss of focus could prove costly when the battle for Championship places reaches a climax next year.
“Things can change so quickly in this league,” he said. “We were bottom after (losing at) Millwall not so long ago and hurting. But now we have moved up the table and things look a lot brighter.
“If we take our foot off the gas, we can be back in trouble. This club has had a lot of disappointment over the last six or seven years and I think the expectation goes up when we have a run.
“The excitement is up at the moment and the confidence is running through the lads. We just have to keep working hard. If we keep doing the right things, we have every chance of being successful.”
Moore made his United debut when United were beaten 2-1 in south London but has not tasted defeat in the competition since. The 26-year-old was a member of the Brentford squad which reached the play-offs in 2013 and added: “There, we ground results out and got late goals which is something we have been doing here of late. It is always a great feeling to get that late goal. It gets the momentum going into the next game.
“The competition for places at this club is so high you have to be on your game every single week. You have to work hard in training, day in and day out.
“The team spirit is excellent, too. I have only been here six weeks or so and yet I settled in very quickly. The lads being a great bunch helped.”
Moore is one of 13 new players signed by United following Wilder’s appointment in May.
“You need the right group together if you want to be successful,” he said. “We have that. Everyone wants to be on the pitch, of course they do. But there are no bad eggs here and everyone wishes each other well. And is pushing each other on. There was a massive turnover so, credit to the gaffer for bringing in the right set of players and the right character. He has that balance and this is a good bunch with a lot of talent. That can only take you in one direction.”
