It is all about striking a balance, Dalot is not an untouchable player, no doubt he has been one of our most consistent players over ETHs tenure, but is anyone under the impression that he is world class?
For Amorim he could easily be a really useful squad player, he is capable at either wing or full back positions, however do we really envisage him eventually being the starter in one of those positions in Amorim's ideal first 11? I do not think he offers enough in either assists or goal threat to justify a starting spot.
So it is how much is he worth and how much are we being offered, it is pie in the sky because I do not believe anyone is proposing this but if there was an option of selling Dalot for £50m this would be an instant cash injection would mean we could amortise the purchases well in excess of the £50m, for arguments sake, if we were interested in Davies then maybe Bayern take £10m now rather than losing him for free in the summer? that would be an example of not only an acceptable trade off as it would significantly improve the 1st 11, there may be other players not Davies that was just an example
In theory if we were to get £50m cash up front for Dalot in January (not happening but) then we can spend £50m upfront in Jan and amortise the rest over the term of the contract, this could equate to up to £250m in purchases in January! (I know it is more complicated as the wages would also need to be accounted for).
Ignoring Davies, we have Malacia, Amass, and Kunkonki in theory at LWB, we could resign Alvaro Fernandez for £16.7m and I do not think we would be any worse off than if we had retained Dalot and would be better in attack, and we would easily have enough to buy another striker.... big issue remaining is who is available in January anyway.
If the Dalot sale were to be an option how it should be viewed as a package with incomings, IMO the same would be true of any player in our current squad, for the right price it should be viewed as what it can do for us.
