- Wingback 1: Geovany Quenda. If we could sign only one player from Sporting CP, it would have to be him (with Gyökeres at the No. 2 spot). Sometimes the obvious signing is the best possible signing.
- Wingback 2: Antonio Nusa. RB Leipzig won't stand in our way if we make an offer that is commensurate with his talent level (it will be a big fee, but alternatives like Kerkez or Aït-Nouri will also cost a bomb).
It's a position of extreme importance, and calls for dynamism, ball-carrying prowess (this is a clear deficiency in the current squad, we struggle to beat people mano-a-mano) and technical expertise in equal measure, and whoop-de-do, both of these players have that in their locker. As talented as some of the best young wingers around, good in possession as well as on counters, and seem quite adaptable.
Also, age profiles that are suited to a brand new project — the former will be 18 years old at the start of next season and the latter will be 20 years old at the start of next season; timely investment in these two could be an astute strategy, considering they are just starting to scratch the surface of their potential. That matches perfectly with seasoned players like Mazraoui, Shaw and Dalot (who could serve as more defensively oriented options in the near term).
The way I see it, we are not likely to compete for the Premier League and Champions League titles right away (on average, that take years of great recruitment and chemistry-building), which gives us the leeway to prioritize and develop lads with extraordinary qualities (and the genuine chance to emerge as dominant performers in the years to come).
Those percentiles are inflated because it's a comparison with midfielders, but the raw numbers are still quite good.
P.S., While I love Garnacho, signing Nusa might make him redundant from a systemic perspective. Garnacho does not boast the sefless characteristics and discipline of a wingback or the close control and combination-play tendencies of a prototypical inside forward in a 3—4—2—1. Unless he unexpectedly adapts to one of those departments, we might have to seriously think about selling him (not because he's not a good talent, but because he's not an optimal fit and could fetch a respectable fee) and signing someone who is naturally suited to the inside forward role (Wirtz is the most obvious solution for the left-sided inside forward role but he will be highly coveted, Güler is suited to the right-sided inside forward role and is not getting much game time at Real Madrid, et cetera). The purpose of a “midfield box” is to dominate in possession, form the basis for relational football and a sustainable supply chain for the center forward, and create numerical advantages, so individual components need to fit specific profiles.
