The forward remains the only out of contract player yet to agree terms with the Blues, after Sean Raggett, Reeco Hackett and Michael Jacobs committed their futures to PO4.
Trio Callum Johnson, Ollie Webber and Paul Downing were not offered fresh terms and also remain without a club, while Shaun Williams has since joined Gillingham.
But with the vast majority of EFL clubs now back for pre-season training, who are the most recognisable free agents still on the lookout for future employers?
We’ve taken a look at the 20 biggest names from the Championship and League One who are yet to find a home.
Here’s what we found.
17. Aiden McGeady
The 36-year-old’s five-year stay at Sunderland was brought to a close after their play-off final victory over Wycombe. The former Everton ace will not without a club for long after reports claim he is closing in on a reunion with former boss Lee Johnson at Hibs. Photo: Stu Forster
18. Connor Wickham
Wickham scored just once in 14 outings for MK Dons following his move from Preston in January. All has gone quiet on the transfer front for the former Crystal Palace striker with no clubs currently in the running for his signature. Photo: Pete Norton
19. Will Grigg
The ex-Northern Ireland international’s big money move to Sunderland in January 2019 failed to live up to the hype - scoring eight goals in 62 outings. The 30-year-old’s career appeared to be rejuvenated at Rotherham last term as he flourished under Paul Warne, playing a key role in the Millers’ promotion. Grigg could be set for a return to the New York Stadium with the United boss regularly speaking highly of the striker. Photo: Stu Forster
