I find Wan Bissaka a difficult player to evaluate. MEN raves about his defensive ability, and he is particularly good at one-on-one defending. However, as someone said above, his defensive positioning can be very poor at times. United's weakness on set pieces can be partly contributed to his weakness in the air. While he did show some improvement going forward, and he showed that he might have the talent to be good on the ball, he still seemed to panic and to give the ball away far too often. He did get forward more frequently and with more effectiveness this past year, but again it was inconsistent. And, if he lost the ball in the attacking half, he did not make the type of effort that I would expect from a defender to get back and defend. You often saw him casually jogging behind the play as the counterattack was moving rapidly towards United's goal. At least a couple of goals could be partially credited to that lack of effort.
He looks the part! He is tall, lean, strong, quick, and he has good pace. We've seen him put in some good crosses, score a good goal, dribble around people, and so forth. It is the terrible inconsistency (except in one-on-one defending) that makes one hope that Dalot or Trippier or someone else might step up or step in.
