I doubt there's a single person on here or at the club who WANTS to lose Rankin. However, what we have is a highly paid, unhappy fringe player, who is a very saleable asset and would command a decent transfer fee.
We desperately a need a central defender and will have to pay a transfer fee and high wage to get the quality needed. If the choice is between having Rankin or a new Dods/Mann, then there's absolutely no contest.
The real question is, should Rankin be featuring more in the first team? We have seen a few times under Brewster left that we are capable of both winning and playing excellent football, without Rankin. Why we haven't been able to sustain that is another matter, and almost certainly relates to tactics rather than any individual player.
It's a case of play him or sell him, just don't keep wasting him in the reserves.
