Wan-Bissaka can be a key player here. He has some extreme qualities that can be well utilised, and is not that bad on the ball either. He carries it well, and is far better offensively than Dalot, who is just terrible going both ways.
I look at Kyle Walker, who I don’t particularly rate as a ‘footballer’ at all, who Pep has used extremely effectively as a cheat code/get out of jail free card. City play high largely on the premise that if any ball goes behind them, it is almost impossible for a forward to outrun and out strength Kyle Walker in a 40 yard race. England did the same in the Euros. Cancelo on the other side is a far superior footballer and is left to get on with that side of the game.
I do not see why Wan-Bissaka could not fulfil a similar role to Walker. One of the issues is that we are not able to play as high as City, and as a result, we have to defend in a different way to them in the main, which perhaps doesn’t suit Bissaka as much. I think for a team that plays on the halfway line, you can easily get a LB like Grimaldo to do his thing on the left and have AWB as your insurance policy. As I said, he’s also not as useless coming forward as is implied.
