This depends on the number of 99% players available for each level. When there are not enough 99% players for the list it contains 98 or even 97 % players. Sometimes when not enough managers at the highest levels the list cointains even 4 star players
Thanks guys! I'll nudge them up to 99% and see if the offers roll in. I would have thought another player at the right level would have still been able to make an offer for them though, even if they didn't appear on the Negotiations list.
Anyway, I've got something to try now so let's see if it makes a difference.
