I still think he goes out on loan again to Girona who should be in La Liga next year. Fernandinho would become the backup and we still buy a top #1.
Fabinho will be the RB cover by the sounds of things m but that doesn't mean a second actual RB would go amiss. If Walker gets injured then we have no right backs, we only have Fernandinho or Fabinho if we get him who's a very different type of player.
If the squad is being shrunk, I think there's definitely room for him.
