Would love Tosin, but I can't see us spending on a CB (I know he's free, but because of that & his homegrown status, Newcastle, Spurs & United at least are all in for him too, so wages & fees will be high).
We'll have Konsa, Pau, Mings and Carlos next season. Unless somebody is sold, I doubt we'll sign one as we're already spending a lot on our CB wages. Konsa probably our best but probably cheapest weekly too.
I think we'll buy a RB and see Konsa at CB again rather than replace Lenglet with a CB. Unless Carlos gets sold, or Mings is miles off it perhaps?
