Kevin Blackwell is keen to bring Wigan forward David Cotterill to Sheffield United on a permanent deal.
The Wales international spent the final three months of last season on loan at Bramall Lane and enjoyed a productive stay in South Yorkshire.
And Blades manager Blackwell is eager for Cotterill to become a full-time member of his squad as he plans a Championship promotion push.
He told the club's official website: "Cotts wants to be here and we would love to have him.
"We're continuing negotiations with Wigan, although there are a couple of stumbling blocks at the moment.
"He made a great impression last season and his pace and trickery would be a real asset for us in the forthcoming campaign.
"I remain hopeful that we can make it happen on our terms, but in football you can never say it will definitely happen because things can change so quickly."
Meanwhile, James Beattie has been left out of the Blades' squad for the pre-season tour in Europe.
The striker, who has been linked with a summer move away from Bramall Lane, is struggling with a calf strain and missed out on training last week.
Blackwell added: "The niggling calf problem, which has caused him a bit of discomfort in previous pre-season campaigns, has forced him to miss a week's training, so we've left him back at the ranch to catch up."
The Blades are scheduled to play three matches during their mini tour, starting with a clash with Ferencvaros in Budapest, then KVK Tienen in Belgium and against Dutch side Helmond Sport.
