It's quite a nuances discussion, whereby we don't actually know a lot of the facts and the issue is Benitez is a very divisive figure who doesn't massively help himself.
The reality is Benitez may have made a decision that while he likes Digne, if he knows an offer is coming in in January he wants to move on. These things happen too. You'd be naive to think otherwise. Chelsea speak to Digne's agent, say they will offer 30m, they unofficially approach the club and Benitez feels that he can do more with the money than the player so indicates he will move him on. The decision is then that he wants to move forward with Godfrey for the medium term so goes on that basis. Again that may be a fallacy and it's just one scenario, but it shows that there is at least one scenario where there is not a lot of blame at anyone's door but an inevitability of football.
On the Godfrey front, the most solid we have been over the last few years have been when we played 4 cb's and Holgate/Godfrey at fullbacks. Again it may not fit people's perceptions, but the numbers don't lie. I'm not saying it's a perfect system, and I'm not saying there aren't better options we can get or that there aren't drawbacks, but honestly I think the upside is better currently. I would play the 4 CB's if fit across the back 4.
If Digne isn't going there is a question as to whether Digne is deployed in midfield. I don't think he's been that bad and I think he would probably be our best wide left putting balls into the box. Gray could play off the right and DCL & Richarlison through the middle.
As a fullback though, for what we need, I am happier with Godfrey at LB than Digne. They play the role differently, but I think Godfrey is very good in that role (in my view far better than he currently is as a CB, so it's not me blowing smoke up his backside either) but he has been good in that role. I still worry he loses too many headers, and probably needs to get confidence and size back a bit before he goes back into the middle.
