Chris Wilder handed two debuts and a first start to three of his new signings at Norwich City and the trio impressed the boss.
Speaking after witnessing James Wilson score his first goal for the Blades, with Ryan Leonard and Lee Evans also impressing, the manager remarked: "Attitude wise I never doubted any of the new lads, because we know what we've signed in that respect and we've signed three players on a permanent basis who I believe will prove to be excellent additions.
"We talk about the market we deal in and we have to work extremely hard to get these lads in, we work hard from the first minute players come through the door and the lads fitted in seamlessly."
Wilder added: "The lads can be pleased with their first marker but there is more to come.
"James Wilson will only get fitter and stronger with games, Ryan we knew could comfortably do 90 minutes, Lee Evans just sat and dictated the game like we know he can and Ricky was unfortunate not to get on the pitch.
"These players are part of the group now and will get better and better the more we work through the week as we aim to produce solid and consistent performances at Championship level."
