Cesc probably wants to be a starter more often than not at his supposed peak. That isn't going to happen here IMO. I would personal want him to be starting ahead of Matic myself, but result come first.
£30m is a joke. He isn't HG & hasn't become much better since leaving Celtic for £11.5m. CB is a position where we have several options. Something needs to be done about a few players before bringing in anyone.
It's inevitable a few will be sold. The question is, how many will go? They could probably cope with losing Silva and one other, but they'll be back to square one should 4-5 leave.
We aren't that type of club. I'd just be worried about the club not going for a similar calibre of player and going for the Willian/Cuadrado's of this world.
