Sheffield United have released several first-team players ahead of their return to the Premier League.

The Blades are back in the English top flight after earning promotion by finishing second in the Championship.

However, they will not keep the same squad that saw them earn promotion, as they look to avoid going straight back down.

Club legend and captain Billy Sharp is leaving, as are Jack O'Connell, Enda Stevens and Kyron Gordon.

The Sun states that Sheffield United are also targeting Lewis O'Brien of Nottingham Forest.

The 24-year-old is on loan at DC United in MLS, but will be back at Forest in July and available for transfer.
