I've got a lot of time for Sanchez and would happily have him as a back up, but i do think the suggestion of sellig him, Dier and Japhet and potentially leaving Tosin with Philips and Dorrington as cover, is absolutely fine. Just my opinion, but i think far too many fans worry about the worst possible injury outcomes, when there are plenty of CB pairings that'll play every minute together this season. With normal luck, it's fairly unlikely we'd need to use a 4th choice CB in a PL match until the next window comes round (think its 15 PL games until Jan window opens - one a week plus Intentional break).We don't really need them both off the books this window and it's way too early to say Phillips or Dorrington are ready for this level. I think they're both out of contract next year anyway so whoever is not sold now will be gone next summer. Centre back is a key position and we need senior established players there. It's not like we can bed them in using early European games either.
