I've abstained from commenting on him since i was not really sure what to think about him, but based on last night performance he deserves to be starting regularly alongside Fred.
He might not be a highlight reel player like Pogba, but he does the simple things of passing, moving and fighting for the ball so, so much better.
Might get ahead of myself here, but i think he might be the solution to our biggest problem, which is dealing with high press. The #1 problem we have with high press is that the link between defense and midfield is not there and we do a whole lot of sideways passing which 90% of the time ends up with one of the fullbacks who then have to try and go forward themselves. Fred, McTomminay, Pogba et al sometimes try to drop deep to help out Lindelof and Maguire with transporting the ball forward in a decent manner, but more often than not they just recycle the ball too and Pogba tends to lose it in dangerous areas. I think the Chelsea and Arsenal games really highlighted this problem. Both played "deep" in the sense that they were always in balance defensively, but they also put pressure on our CB's, which meant that our game plan completely broke down.
Van der Beek might be a revelation here, because hes adept at positioning and short passing so it makes it much easier to get the ball from defense into a good attacking area. If we regularly can beat the first line of press we are at a big advantage because A: The forwards of the other team will be gassed by 60 mins and B: We will stretch the other team and create more openings for Bruno/Rashford etc to create chances.
