James Wilson says joining the Blades was an 'easy decision to make'.
The Welsh international penned a two-year deal with United on Tuesday having rejected a new contract at Oldham Athletic and he says his mind was made up once he received an invite to come and train with Chris Wilder's squad.
The defender remarked: "With a club like Sheffield United, there's always a clear objective.
"We know what we want to do and what we are expected to do. The manager told me I have a point to prove and I completely agree with him.
"I'm not quite sure why I haven't achieved everything I probably should have done yet, but there are always reasons.
"I felt like I did well at Oldham, but that was a club that was struggling and so you don't quite get the same plaudits which I completely understand.
"I had options, though, so I must have been doing something right. Anyone who gets the opportunity to come here would jump at the chance."
Wilson has been training with his team-mates since United returned for pre-season and he is already impressed with what he has seen.
The 27-year-old, who started his career at Bristol City, also has family in the area and is confident of a bright future in the steel city.
He added: "Over the last few days I've seen the difference in the facilities and also the training. It was an easy decision to make.
"Bramall Lane is quality, the fans are too. It's going to be different playing in front of 20,00 but I'm looking forward to it, definitely. How could you not?
"I've got family in the city, so I know it is a fantastic place to be in."
