turn loaned Swindon Stephen Darby, who later scored the winning penalty that put Swindon through to the 2009–10 play-off final. Simon Ferry and Paul Caddis were loaned from Celtic, both having since been signed on permanent deals from the club. Wilson loaned Manchester City striker David Ball for the 2010–11 season. On 2 March 2011, Wilson resigned his post after a poor run of form that had seen the club slip into the relegation zone. Sheffield United On 27 May 2011, Wilson was appointed the manager of Sheffield United. The appointment was greeted with some dissatisfaction amongst the fans, as approximately 400 gathered outside Bramall Lane to voice their anger at the appointment, particularly considering his links as a former player and manager of bitter rivals Sheffield Wednesday. Disapproving chants against his appointment could be heard throughout the announcing press conference.

As part of the restructure of the Blades managerial setup, captain Chris Morgan was promoted to a player-coach position. Morgan had played under Wilson during his earlier years at Barnsley. A couple of weeks later, Wilson appointed former Sheffield United player Frank Barlow as his assistant. Wilson made a positive start at the Blades, winning his first league game in charge with a 2–0 victory over Oldham Athletic. This was then followed up by a League Cup victory over Hartlepool United and a 2–0 home victory over Brentford in Wilson's first home league game. Wilson was named League One manager of the month for December 2011 after managing the Blades to league victories over Rochdale, AFC Bournemouth, Notts County and Hartlepool United. Despite the Blades scoring 92 league goals and accumulating 90 points (finishing 3rd) in Wilson's first season in charge, the team lost on penalties in the 2011–12 League One play-off final against Huddersfield Town. Wilson won the League One manager of the month award for October 2012 after guiding the Blades into the automatic promotion places, including a 19-game unbeaten run in all competitions.
