Certainly this forum wasn't without its prior criticisms of Wan-Bissaka before he joined United. The argument followed that Wan-Bissaka looked offensively and technically deficient due to the limiting factor of playing for Crystal Palace in a highly defensive system. It was thought, by some, that Wan-Bissaka would look much better in a team that (a) set up up to provide him ample opportunity to attack, and, (b) was surrounded by overall better team mates.
What we're left with is precisely what most of RedCafe already knew. He was defensively a giant, but offensively ineffective.The scouting team determined that the pros far outweighed the cons and that offensive productivity could be improved, however, it's easier said than done. Even in a highly functioning side, Wan-Bissaka would have many of the same issues going forward; namely, he cannot cross the ball with any general threat, nor is particularly adept at feeding balls into feet for strikers calling for it. For that reason, James has to play on the right and be the one to keep width, since AWB cannot overlap/underlap with any intuition, and any full-back wide play is forced to come from the left.
