Ole has changed the way how fullback should attack and fullback is slowly adapting to his tactical. Young didn't make a lot of crosses but is making more square passes and cutback, I think Dalot would be excellent going forward on the right flank, especially with his pace and dribble, he'll be beast, he created that goal by beating a man with his pace that open space for Rashford to exploit space.
Dalot haven't had a lot of games in senior but learning his trade in LB, he'll be always inconsistent. When he develops his games and fully adapted to the pace and physically of the premier league, he'll be a world beater, he has talents to be the best fullback.
