I'm surprised we need so many good CBs, but perhaps Greer is expected to slow down soon. The club didn't have to give Dunk a new contract, so I assume they wanted all 4. It's unlikely that none will be injured or suspended, so with 2 playing, and 1 on the bench, they should all get a chance...
If what's been posted about him so far is true, he doesn't sound like the sort to suddenly go to a club that have shown no interest in him. Money talks, but he could have gone to Swansea if he just wanted money.
There are no guarantees that we'll get what we want, but they are trying to spend it.
Has it been relaxed? I didn't know that, have you got a link if it has?
