In my opinion and given what happened last season it would be crazy for us to go into the season with only 4 centre backs especially as 3 of them are coming back from serious injuries. I don't want to be hearing talk of Fabinho being 5th choice. You just know it wouldn't be too long before we see Fabinho at CB again. For me we either keep Phillips or Davies as 5th choice. No more square pegs in a round hole.
If Davies couldn't get a game post January when we needed a body, he isn't getting any games as a 5th choice now, nor would we depend on him given that he clearly isn't good enough. Imo if we get what we want for Phillips, he'll go, regardless of 4 centrebacks and/or Davies leaving. Imo Rhy's Williams will more likely to be 5th.
We've always gone with 4 CB's, bar last year.
-Van Dijk,Lovren,Matip,Gomez
-Lovren,Matip,Gomez,Klavan [it became 5 mid season once we bough Van Dijk in Klavan's last year here]
