That's fact but doesn't justify why Bissaka isn't known as being good going forward.
If you actually watch the game and pay attention on it, you will realise that when Shaw delivers the ball, his delivery more on point either it was in dangerous area but none there or it was received by our players but wasted by the received players.
On contrary, Bissaka's delivery is less on point aka less quality, you often see his delivery being way too far from dangerous area such as over-hitting it, end up crossing the ball to outside penalty box, and etc. Reminds me of Aurier 19/20, had lot of assists but if you watch him, he had so many shit crossings.
Have to give credit to manager managed to find a system that allows Bissaka to produce decent amount of end product. Turning player who is not supposed to be good going forward into much better on stats.
