Sheffield United have signed Blackpool midfielder Chris Basham and Walsall centre-back Andy Butler on three and two-year deals respectively.
Basham, 25, was out of contract with the Seasiders, having made 42 appearances last season.
Butler, 30, who has spent the last four seasons with the Saddlers, turned down a new contract last month.
The Blades have now made four signings this summer, having also brought in Jamal Campbell-Ryce and Marc McNulty.
Sheffield United boss Nigel Clough told BBC Radio Sheffield: "I'm very, very pleased with both of them.
"There was a lot of interest in Chris from clubs in the Championship because he is a very consistent player who can play in a number of positions. It's great to have him on board.
"Andy is vastly experienced at this level and he's a potential captain for us.
"You need leaders on the pitch to make sure you're not just relying on one person."
