The 2010-11 season was Sheffield United's third consecutive season in the Football League Championship after coming 8th in the 2009–10 season. It was Kevin Blackwell's third season in charge of United; however, he left Bramall Lane in mid-August after losing at home to QPR. Gary Speed was named as his successor but lasted only until December when he left to take over the Wales national side. Following a short spell as caretaker by John Carver, Micky Adams was appointed manager for the rest of the season. It was a turbulent season off the pitch and results declined, with Adams being unable to save the team from relegation to League One for the first time in 23 years.
