Sheffield United have completed the signing of Scotland midfielder Barry Robson, subject to international clearance.
Wilson told the club's official website: "When someone of his experience and quality comes along you have to sit up and take notice.
"I'm delighted a deal can be completed, especially given the fact that he's been back in the country less than a week.
"He gives us options in offensive positions, he will score goals and be a supply line for others."
Robson joins Jonathan Forte in signing for the Blades on transfer deadline day.
