7. Murat Ulker
Ulker - chairman of the company that supplies McVities - was reportedly willing to pay £220m but he soon denied his interest and the involvement of Tom McLoughlin, who claimed to be the family's representative in October 2017. Photo: Getty Images
8. Amanda Staveley
Staveley reportedly tabled three bids for the Magpies - ranging between 250million to 350million. While things looked rosy, Ashley pulled the plug in January 2018, labelling it frustrating and a "complete waste of time". Photo: Getty Images
