I think we should invest in our defense. Is there a Nuno Mendes type player we can sign?
At this point, considering the players we're interested in, I'd go with Mazraoui (free) AND Azpi (free) for RB, Lisandro Martinez (35M?) and Christensen (free) for CB, and Gaya/ (if he doesn't extend with Valencia, otherwise) Grimaldo (25-30M) for LB. So we're looking at rougly 60M and we get 5 new players for that, and we strengthen in all three defensive positions. We can honestly get this kind of money just from our defensive sales. Dest and Lenglet alone could cover it, getting 30M for each is doable. If we need more, get a few millions for Mingueza too and sell him too (maybe with a buy back) instead of just loaning him, the latter being the minimum that should be done with him. Garcia to stay as the 4th CB, as I don't imagine we'll be selling him yet no matter what. Roberto leaving for free, and Pique hopefully retiring this summer. If we keep Balde, we could sell Alba too, but that's probably too much to expect.
As for the Nuno Mendes type, I honestly don't know. Feels like the best course at this point would actually be to give Balde an actual chance, as he can become that type of a LB (for us). And since we don't seem to be looking for that type of LB to buy, since both Gaya and/or Grimaldo are both different type of players. Plus keeping Balde would almost certainly mean Alba leaving, so that's a win-win in my book. Cause I really don't want Alba spoiling the mood in the locker room, and given his (cry baby) character you just know he'd start kicking up a fuss the moment Gaya/Grimaldo would become starters ahead of him, which should be asap. So better to have Balde there, but this time actually using him and giving him minutes to fit that rotation/backup role, of course.
