What's with the insistence on using a defensive oriented fullback like Fosu-Mensah in the era of Carvajal, Kimmich, Semedo and co. This lad is a proper fullback, a burgeoning thoroughbred, as it were: good in both offense and defense, and potentially very, very good when you consider his skill set and maturity at a young age. Whereas Fosu-Mensah's offensive production is quite erratic — which isn't all his fault, to be fair to him, because he is more of a defensive or midfield stopper who's being asked to play out wide - and not a specialist.
