Sheffield United's coaching staff have been discussing the Leeds striker lately. Is his position under greater threat from the 21-year-old?
In the past week, both Sheffield United boss Nigel Adkins and the Blades' Under-21 coach Chris Morgan have discussed Leeds United forward Billy Sharp.
Neither have suggested they have made a move for the 29-year-old but both have been coy and hinted that Sheffield United would actually rather like to re-sign the striker.
Indeed, Nigel Adkins made it sound as though he is biding his time before making any Sharp decisions (pardon the pun).
Morgan, meanwhile, stressed that the Leeds man would 'love nothing more' than a United return.
The 21-year-old adds another name to the Whites' final third but, of the rest of their forwards, there weren't that many goals shared between them last term. Will Uwe Rosler, then, look to sacrifice a striker in favour of the Scot?
Should the Blades' links with Sharp continue, the 29-year-old may well be the man to go if so.
The alternatives, of course, are to offload Steve Morison - or keep everyone on board. The latter may just depend on the system Rosler plays. With his preferred formation in the past being a 4-3-3, however, someone could be making way for Erwin...
Will it be Sharp?
