McGoldrick is eager for the season to start after ending a five-and-a-half-year association with fellow Championship side Ipswich Town in the summer.
He says that Wilder’s management style is similar to that of former Tractor Boys’ supremo Mick McCarthy, who initially signed him in 2013.
The former Republic of Ireland international, 30, penned a one-year contract last week and celebrated the occasion by notching a fine goal against three-times European champions Inter Milan during the 1-1 friendly draw.
He also netted in the 2-0 win at Doncaster and is targeting a successful campaign as the Blades bid to build on an impressive first season back in the second tier after a six-year hiatus.
Wilder’s side finished 10th last season, just six points shy of the play-offs.
“I’m chomping at the bit,” McGoldrick told The Yorkshire Post. “I’d been at Ipswich for five-and-a-half years and sometimes you can go a bit stale so you need a change.
“I’ve come to sign for a big club and I’ve been given a one-year deal and who knows after that?
“I’ve got to go and get that extension now because I want to stay here for as long as I can. I love the way the manager sets the boys up to play.
“I played some of my best football under Mick and I’ve got a lot of time for him.
“They (McCarthy and Wilder) are quite similar characters: both Yorkshiremen and both straight down the line.
“What you see is what you get and that is a great trait to have.”
McGoldrick admits he enjoyed his time in Suffolk but that he was ready for pastures new.
He was released following the arrival of new chief Paul Hurst and jumped at the chance to head to South Yorkshire, initially on trial.
“I picked up a lot of injuries and kept coming back but it was hard on my body,” he added. “It got a bit stale at the end.
“I want to impress here and I’ve got a little bit to prove.
“I’ve got a lot of legs left in me.
“It’s quite a breath of fresh air to come somewhere completely new.
“I believe in my ability and I think I’ve got a perfect set-up here at Sheffield United.”
