Too slow and poor in final third atm for a winger. Shooting is poor. But with experience and confidence I think he could be decent winger, a rotational option. Good in tight spaces. Maybe a mezzela for now. But most wingers would struggle in our football. You have to have the physique of Leao since they are so far away from goal.
I say keep, for pragmatic reasons. We have no money, don't know what more damage will come from the "investigations" sanctioned from UEFA through Calcio. I expect more to come to scare other clubs from ever bullying them again. So we will have no budget and expiring contracts and the players we don't want no one wants to touch even for free. So, keep, we need to have a squad and Soule has shown versatility when stepping in as RWB, RW, AM, SS, and CM.
