I think we need 5 senior CBS next season (instead of the normal 4): Van Dijk is coming off a serious injury and might have set-backs or his playing time might be needed to be managed and other CBs have potential injury concerns as well. If we sign Konate, then one of Matip, Gomez or Kabak will probably need to leave (I assume Phillips will stay as a back-up).
If the medical team thinks Matip is likely to fully recover and not be permanently crippled by his back issues, then I would actually consider selling Gomez. If he loses just a bit of pace due to the accumulation of all these serious injuries and age, he will become a very average defender very quickly. And as the England international and home-grown player, he will command the best selling fee compared to any of the others.
Oh, and I completely forgot about Davies. No idea how he figures in all this. Maybe goes out on loan?
Appaz there are some Premier League clubs and Celtic that are looking at Davies should we consider to sell him.
So I'm guessing this could be one were we make a profit but with the player not even starting a game for us..
