So this season has been pretty awful for a big signing to play so little and DVB hasn't looked that confident and at the best of his ability in some of the matches he's played. This post is not to argue against that.
However I do think its interesting to look at the areas where he has still provided something, even if its not what fans wanted
When we look at this for example

The players DVB is statistically similar to are plenty of players who have been favourites on the transfer forum in the past. N'Dombele, Valverde, Llorente, Oliver Torres and Nico Barella. And as we can see, in some areas he's hit a very high percentile for midfielders.
84% for non-penalty goals, 82% for assists, 97% for expected assists which would suggest he's been unlucky with teammates missing some great chances he's set up...
Touches in the opponent's area 99%, progressive passes received 97%
There are also areas where he has faired weakly compared to other midfielders.
However, considering he hasnt been given a run in the team and clearly hasnt been at his best the fact that he's set up good chances, got into the opponents penalty area and got on the ball, scored goals and been in good positions to receive passes are all good signs. As we can see, he's done well in those specific areas.
The main area of concern would be making so few progressive passes himself. As we can see from the numbers, he's extremely low here for a midfielder. That just says the role he's trying to play is to be beyond the ball and he needs players to feed it to him in the attacking positions. He's making the runs, he's setting up the chances, he's scoring some goals. He needs someone else to play the ball into him. At the same time, he wouldnt have 97% progressive passes received and 99% touches in the opponent's box if our players werent doing that. But I still think we can do it a bit better
