Enda Stevens insists the Blades aren't a far off being really competitive in the second tier, despite consecutive away losses.
Speaking prior to Saturday's early derby clash against Barnsley at Bramall Lane, the former Portsmouth man remarked: "It's been a tough start, we had three difficult games, including going to the pre-season title favourites and the early leaders who are flying and Brentford who had a very good season last year.
"We just going to have to get up to speed with the division and the intensity and quality of the opposition.
"It's a long time since I've played Championship, but this group is well capable. We were particularly unlucky at Middlesbrough."
Stevens added: "At Cardiff we were in the game and created chances, but we need to improve at both ends of the pitch, we need to keep more clean sheets and score goals.
"The division is more intense and physical, the quality has gone up and up and it's like a mini Premier League now, it's just so competitive."
