There is a theory that the trend in football is moving back towards full backs who are more natural defenders rather than basically attackers, Liverpool get away with it to an extent because they have a midfield that don't really flood forward into attacking areas so it's all about having the right balance.
The attacking part of his game isn't fantastic but I don't see a huge difference between him and Dalot they both put in the odd good cross in, both have an ok shot on them and both have ok dribbling skills.
The top full backs have both and a lot of he attacking side of it is just having the fitness to be there when you need to attack and recover when you need to defend and AWB has that so I think over time he'll improve his final ball and decision making.
