Here’s a look at all the players that the Blades have been tipped to sign so far, and how likely they are to sign...
1. Stephane Bahoken - Angers SCO
Nothing in it: The Cameroon striker had a solid season in Ligue 1, leading him to be linked with pretty much every top tier side

2. Macauley Bonne - Leyton Orient
Agent talk: He's been linked with a number of clubs from the Blades to Leicester City, which suggests his agent is trying to get the 23-year-old's name out there.

3. Kieran Dowell - Everton
Possible: The Toffees will be keen for their youngster to play regular first team football next season, and a return to the Blades could make that happen.

4. Josh Brownhill - Bristol City
Possible: The tenacious 23-year-old definitely appears to have the attributes required to be a hit for the Blades, but competition from Brighton could prove problematic.
