I like Mina but of all four central defenders he's the one I could see leaving. I think all four are good without any of them being really great (Godfrey may get there but he's not there yet). It wouldn't be a priority, but if we got £20m+ offer for Mina I could see them accepting to try and fund that really great defender coming in. Holgate will probably stay - despite probably being the weakest of the four - as his versatility is really useful and he contributes to the English quota.
