David Weir says the reshaping of his squad is nearing completion.
Speaking at Thursday night's 'Meet the Manager' event at Bramall Lane, the Blades boss revealed he wants a close knit group of players who all have the belief and motivation that they are close to first-team action.
After seeing Lyle Taylor officially become a Blade on Wednesday, Weir commented: "I am happy with what we have got at our disposal now, but we, of course, are always looking to improve should the right player become available.
"We would like to sign one more, possibly two if a couple of players leave, but we have to remain realistic. I want a tight squad, with players who know they can contribute and ones who are in contention to play regularly.
"From experience, I know it would be counter-productive for the group if we have too big a squad and certain players know they aren't likely to play on a Saturday afternoon.
"Sheffield United is a big sell when you meet potential recruits and they know that signing for the Blades is a fantastic opportunity to further their career.
"There is still room to work, both in terms of incomings and outgoings, but it won't be a case of wholesale changes at this stage."
When asked about identifying potential transfer targets, Weir said his relationship with United's Head of Football Operations is a healthy one, with the Gaffer saying he works with an inclusive philosophy.
Weir added: "The more people involved in terms of recruitment the better chance you have of getting the right player and making the correct decision.
"I lean heavily on the excellent work of John (Stephenson) and he has been fantastic to work with since my arrival.
"We work to a certain criteria when looking to recruit players, but ultimately I have the final say as it is me and my staff that have to work with them."
