The 29-year-old caused elation among Blades fans, although the Leeds faithful were quite split on news of his departure.

Leeds United and Billy Sharp is proof that sometimes love just isn't enough. #lufc— Katie Wadsworth (@ktjwads) July 25, 2015
Not bothered at all about Sharp leaving. Limited striker who never took his opportunities. Width is what we need. #lufc— Robert Kelly (@RKelly7771) July 25, 2015
Dissapointed Sharp has left but clearly not the same player he was 3-4 years ago. #lufc— Matt Staniforth (@MattStaniforth) July 25, 2015
Surprised so many people are upset about Sharp. Lovely guy, but he's not the answer for us long term I don't think #lufc— I Hate Leeds (@ihatelufc) July 24, 2015
There is an argument to be had that Sharp was utilised poorly at Leeds - and that all the managers who played their part over the course of the season failed to get him in the areas where he can be dangerous.
In the Championship, there are few more proven goalscorers than Sharp and it's surprising that Uwe Rosler didn't think about partnering Chris Wood with him for the coming season.
Nevertheless, for Sheffield United, it's a very good signing ahead of what should be a promising season for them. The competition at Leeds, meanwhile, is plentiful in the final third.
Nigel Adkins knows him well and knows how to get the best out of him, so he could be a very decent bet to be one of the top goalscorers in League One next season. For Sharp, it's a chance for a homecoming and a chance that will hopefully see him return to his best.
