It’s a bit weird since we have LB covered so far with Escudero and Carole, however, the management is definitely seeing something BIG in Arana, so who knows.
We should be focused on a striker and a CB/RB (urgently), and potentially a goalie (less urgent).
Who knows when Pareja and Carrico will make the 100% comeback after their surgeries. I wouldn’t count too much on Pareja, first because of his age and prone to injury (also had an ACL in 2015), and also not counting on Carrico for this season, very prone to injury.
If we get a RB in January, or ideally get Aleix Vidal back, then Mercado can be shifted to CB to help Kjaer and Lenglet and then Vidal can perform at RB and pair with Navas/Sarabia.
