Nigel Clough has described himself as 'delighted' with the additions of Andy Butler and Chris Basham.
Speaking after the announcement on Thursday that the duo had signed two and three-year deals (effective from 1st July) respectively, Clough outlined what both will add to his squad, whilst admitting the Blades have fought off plenty of interest from elsewhere to secure the services of Butler and Basham.
On the signing of the former Walsall skipper, Clough remarked: "Andy is vastly experienced, a leader and an excellent character, both on and off the field.
"That is important to what we want to achieve next season. We want three or four leaders with captaincy experience within the squad, that way we aren't just relying on one person.
"Andy has been a consistent performer at Walsall for a number of seasons now, he could have stayed there or moved elsewhere in League One and even the next division up, but thankfully the lure of Sheffield United convinced him this was the right move at this stage of his career."
On the recruitment of 25-year-old Basham, formerly of Blackpool, the Gaffer said: "We have fought off plenty of Championship outfits to bring Chris to Bramall Lane and we are delighted we have managed to get the deal over the line, as we are with Andy Butler.
"Chris probably would have liked to have stayed in Championship, but he appreciates what we are trying to build here and again he jumped at the chance to be a part of it.
"Our end to last season will have made several players sit up and take notice of Sheffield United and that obviously has played a part in our recruitment to date, particularly given Chris's circumstances and other potential options."
Meanwhile, Clough concluded by revealing that a contract has been 'agreed' with Ben Davies, with the Gaffer hopeful of wrapping up a deal soon.
The Blades boss finished: "We have agreed something with Ben, so now it is just a case of getting him in and signing it off.
"We also hope to have a answer from Chris Porter in the near future, by making him a contract offer shows we would like to retain his services for next season, but it is now down to the player."
