Guehi won't be #4 CB ... he'll be #3 vying with Konate for #2 and subbing in for VvD (since LCB is his primary position) and replacing Konate when he's inevitably injured.
I’m obviously not making myself clear in these posts.
I don’t see Guehi as 4th CB - I see him as playing significant minutes in rotation with Virgil & Ibou - kind of like, as a example, Jones does with Mac & Dom.
The question is about a 4th choice CB.
Do you have Gomez as the nominal 4th CB, bring in an older player to cover in emergencies or bring in a younger player to develop but is good enough to play if required.
I don’t think you rotate your CB’s much - 3 players covering 2 positions I could see, but 4 is too many to rotate regularly, so the 4th CB is likely to play domestic cup, CL & PL dead rubbers and spend a lot of time either sitting on the bench or watching from the stands and only used as a emergency.
It’s the equivalent position of the 3rd GK for me.
Gomez is ideal because he can cover both FB positions too and even DM in an emergency and is good enough to actually hold down a starting position in the first team - he’s just always injured and therefore an increased risk.
Bringing in an older player is likely to be a compromise on quality or more likely to require a valuable OS slot, which, as I’ve previously mentioned “could” limit us in other areas.
Bringing in a younger player, particularly one that still qualifies as an U21 is likely to be expensive and we might not be able to give the player much in the way of game time to develop.
Slot’s comments seem to suggest more towards leaning to risking Gomez and using the likes of Endo and Gravy as further back up - which I’m ok with IF we sign Guehi or someone at a similar quality level.
I find the older player option less appealing because I’d want the player to be a good fit for what we want at CB - tall, strong, fast and technically competent enough to progress play through passing or carries.
We sort of know if the player isn’t good enough, Slot just won’t play him anyway.
My preference is to sign Guehi and bring in a younger player in the 19-21 range that has a high ceiling and we can spend a season drilling him in our defensive structure with next season being either more game time if Konate goes or a season long loan to a good team for more game time.
The 4th CB doesn’t matter as much as long as we sign someone like Guehi though.
