It's extremely pleasing to see the performances Shaw is putting in these days. He has a great combination of physical and technical traits which make him a great asset and one of our very best players. I agree with those who are saying he has been great for at least three out of the four last seasons. I prefer him at leftback though, even if he is amazing in central defense. The reason is that, as good as Malacia can be, Shaw offers a physical presence in our box. This prevents opposition forwards from targeting our fullbacks on dead balls or crosses, because Shaw can deal with those far better than Malacia can. Also, Martinez' passing is a lot better than Malacia's, so it is for the best if both Martinez and Shaw are in the side at the same time. Having the option of playing like we did yesterday is great though, because different options for how to play leaves us less vulnerable to injuries and more capable of dealing with potential fatigue.
What I think used to hold Shaw back at times, apart from injuries, was his propencity for turning off at moments in the game (explaining why some players have outmuscled or outrun him at times, when such occurences seem unnecessary). This season though, he has been switched on at almost all times. Perhaps Shaw is a player who benefits a lot from the disciplining influence of Ten Hag? To me, he seems like the kind of character who is less able to discipline himself (re: the rumours about his diet and staying up all night with his mates). Also, the improved defensive structure Ten Hag has managed to develop in the team, helps Shaw with this. Of course, Shaw also contributes towards it.
