We aren't forcing him to stay if no one makes an offer.
We could tell him that and he can leave in January or stay on if we look like going up.
I do see what you're saying, but if he doesn't want to be here he doesn't want to be here- regardless of whether anyone wants him or not. Plus it's clear clubs do want him, the sticking point seems to be the price. If he ends up not getting a move, he'll feel like we played hard ball in order to force him to stay. We don't need any more disruptive influences this season. Plus I don't think he'd ever have come without his mate Mbia from OM, who was conspicuous by his absence at the weekend- and is presumably off as well.
