Premier League newcomers Sheffield United have signed Nottingham Forest midfielder Ben Osborn.
The Blades have paid an undisclosed fee for the 24-year-old, who has signed a three-year contract at Bramall Lane.
Osborn came through Forest's youth set-up and, after his debut in 2014, played 230 games for the Championship club.
"We are putting together a group that's got to be competitive in arguably the best division in the world," said Blades boss Chris Wilder.
"He's been a fantastic player for Forest in the Championship and I know for certain that two or three clubs in January were sniffing around to take him."
