Andy Butler says his decision to join the Blades was a 'no brainer'.
The 30-year-old penned a two-year deal at Bramall Lane recently, having turned down a new contract offer from Sky Bet League One rivals Walsall.
The Doncaster-born former Saddlers skipper believes the move back to South Yorkshire has come at the right time in his career.
The centre-half remarked: "I received a phone call from Chris Morgan at the end of the season and he just wanted to know if I would be interested in speaking to the Gaffer, of course I was.
"Walsall wanted to keep me and made me an offer, but when a Club like Sheffield United put an offer in front of you it is hard to turn it down. It was a no brainer really.
"Geographically this is a good move for me too. Travelling from Doncaster to Walsall everyday was starting to take its toll on me. Having some valuable family time and getting an opportunity to represent Sheffield United means this was a win-win situation for me.
"I am looking forward to every minute of being a Blade, I know there is a level of expectation at this Club which is understandable, but I am confident we can handle it, the Gaffer has signalled his intentions with his signings to date."
Butler is determined to hit the ground running in S2 and is confident of earning a place in Nigel Clough's starting XI, adding:
"I want to play regularly, I haven't come to sit on the bench, but I know it will be difficult to dislodge Harry (Maguire) and Neill (Collins), but you have to believe in your own ability.
"The Gaffer knows what I am about and I am determined to take my chance in pre-season and prove to the manager that I deserve to start come the 9th August."
