One of United's newest recruits is excited about the prospect of working with David Weir and playing at Bramall Lane.
Stephen McGinn, formerly of Watford, signed a two-year deal with the option of a third last week, and is keen to get to work in South Yorkshire.
Of his switch to the Steel City and his previous memories of his new club, the 24-year-old remarked: "This move was something out of the blue, but once David (Weir) was appointed as manager it picked up pace quickly.
"When a club like Sheffield United shows a genuine interest in you, you want the move to happen as quickly as possible. I was keen to come here and I am determined to hit the ground running throughout pre-season.
"I can remember playing at Bramall Lane for Watford, who were 1-0 up with 10 minutes left. United had a succession of corners as they chased the equaliser and the atmosphere and support was something I haven't forgotten, the place was rocking.
"The new manager has made a fantastic impression on the lads already and everyone can't wait to get started with the pre-season games."
Last season, McGinn scored against the Blades whilst on-loan at Shrewsbury Town and the midfielder says his spell at the Greenhous Meadow was crucial to him as he banished memories of a serious knee injury, sustained whilst a Hornet.
He added: "I had a bad knee injury against Doncaster Rovers a couple of years ago, but I have worked extremely hard to work my way back from that.
"I enjoyed my time at Shrewsbury last season, most of all proving to everyone I was back and able to perform consistently. After last season I am confident I am fully over that injury and am genuinely excited about the future with Sheffield United."
