Miller, who moved from Crewe for an undisclosed fee, was one of three new signings unveiled by the Blades, with free agents Matt Hill and Tony McMahon also adding to manager Danny Wilson's options. "It is an exciting move for me, personally, because Sheffield United is a massive club and one that will be looking for promotion this season," Miller told the club's official website. "At Crewe the aims and level of ambition is a lot different, but here I know the expectation is to get back to where everyone believes this club should be, which is the Championship at the very least." McMahon added: "My agent called me a couple of weeks ago to tell me that Sheffield United had made an offer and after considering my options I decided this was where I wanted to play my football."
