I get that AWB wasn't very forward thinking, particularly at the start of the season, but I don't subscribe to this view that he's a poor footballer. I say this with a number of points in mind.
Fatigue:
He started giving away passes about the same time as much more established passers in the team. Even his famed tackling took a nosedive, so why is it put down to fatigue for some players, and not for the other? Particularly considering his position means he needs to get up and down the pitch quickly and repetitively through a match?
Passing prior to the team running on fumes:
Yes, he did not support the attack as much as we would have wanted before the break, but he wasn't giving the ball away - even against high pressing teams like City and his passing was generally decent.
Attacking Success:
After the break, and just before the whole team gassed, when he decided to start joining in the attack, he started adding a lot more up front and his passing and crossing were fine. Again, as the team tired though, so did he, and the passing of the whole team slumped along with his (apart from a few players up front). With rest, it will improve again I'm sure.
Ungainly running 'gait':
We can all agree he looks ungainly when carrying the ball, but it doesn't mean he has poor control considering the ball doesn't get nicked off him that often. The appearance doesn't always tell the whole story. That way of running with the ball is similar to that of many lanky and long legged players. See Crouch, or better still Arsenal's Kanu for instance: they looked both ungainly but had very good ball control.
I suspect that even as Wan Bissaka improves offensively, his dribbling will still appear ungainly. If he beats his markers and puts good crosses in which lead to goals, that's fine by me.
