If we stick with four at the back then at the Emirates it'll be Hwang behind Strand Larsen and Rodrigo and Sarabia either side, as it was vs Leipzig.
If we change to three CHs (I know we're trying to move away from it and I welcome that, but it's Arsenal away and Cunha isn't available it seems, so we might go more conservative) then one of Rodrigo or Sarabia will miss out.
I'm not against us directly replacing Neto but we do have a LOT of wide players in the squad (opinions will vary on how good they are). We need a CH far more as Yerson has never played PL football and Toti has his limitations, while the other two CHs do instinctively look to be too slow to play in a pair. We also need far better than Bentley to challenge (or replace, who knows) Sa and it'd be good to have a proper back up to/competition for Strand Larsen as neither Cunha nor Hwang are really out and out strikers.
With this money then we should be able to fill those gaps with quality, if we don't then it'll be a failing on the club's part.
