Chris Wilder has moved quickly to bolster United's goalkeeping ranks for next season with the addition of Wes Foderingham on a three-year contract.
The 29-year-old, who has featured against the Blades for Swindon Town in previous seasons, signs at Bramall Lane having left Glasgow Rangers at the end of May.
"I'm delighted to join Sheffield United," Foderingham told sufc.co.uk. "It is an exciting time for the club after an incredible first season back in the Premier League. I'm looking forward to meeting the team and can't wait to get started."
Foderingham began his career in the capital with Fulham but signed his first professional contact with Crystal Palace and had a number of loan spells to further his development. In October 2011, he joined Swindon Town on loan and impressed manager Paolo Di Canio, keeping nine clean sheets in 15 games, prompting the Italian to make the transfer a permanent one for an undisclosed fee in January 2012.
During his time at the County Ground, the former England youth international came up against the Blades in the dramatic play-off semi-final contest in May 2015, which ended 5-5 in the second-leg, although Foderingham left Town after they failed to overcome Preston North End in the final at Wembley.
Having amassed over 150 starts for the Robins, the Hammersmith-born stopper moved north of the border in July 2015, penning a three-year deal for the Ibrox club. During his first three campaigns with the Gers, Foderingham was consistently first choice and made over 100 appearances for the Glasgow club, including five last term.
United's goalkeeping coach, Darren Ward, commented: "We have followed his development for a number of years and are delighted to be able to bring him in to bolster the goalkeeping department to give us options and competition for places. Wes is an experienced 'keeper and we look forward to working with him."
