Former Nottingham Forest loan striker Billy Sharp has been linked with a surprise move to the Reds' bitter East Midlands rivals, Derby County.
The 37-year-old is a free agent after being released by hometown club Sheffield United at the end of last season, following the Blades' promotion to the Premier League. He only scored three goals in 45 appearances last term, but 30 of those were off the bench, with the veteran scoring 15 in the previous campaign as United lost in the play-offs to Forest.
Sharp spent the 2012/13 season on loan at the City Ground when he bagged 11 goals in 40 appearances.
