Harrison McGahey is hoping United can make it six games unbeaten when they head to Essex to face Colchester United on Tuesday night.
The young centre-half who has started every league game for the Blades to date following his summer switch from Blackpool, says Nigel Clough's side are improving with every game and he sees no reason why that won't be the case against the U's.
The 18-year-old remarked: "We had a disappointing start, losing the first two games in the league put us under pressure, but since the win at Peterborough we have steadily improved.
"We have kept two clean sheets at home in 1-0 wins and the confidence is beginning to grow.
"The Gaffer keeps saying about going on a long unbeaten run and we certainly have a start, now we must kick on and look to go unbeaten in the next five or six matches and see where that takes us."
On his own start to the season, McGahey admits his progress has surpassed his own expectations.
He concluded: "I didn't expect to be a first-team regular this quickly when I signed in the summer, but I know I need to keep learning and improving.
"I just got my head down and worked hard in pre-season, looking to show the Gaffer what I was capable of and thankful he saw enough to give me a chance, so I have to be grateful for that.
"But the more senior players within the squad have also been a tremendous help to me in these first few weeks of the season.
"I just want to keep playing well and hopefully my performances can keep me in the team as things continue to progress."
