Very interesting to see that. It's noticeable that Bruno has to vacate the middle in order to receive the ball from McTominay and Fred. When Pogba plays, his ability to beat a man and his vision to thread a pass means Bruno can sit tight in those central areas because he knows the ball will eventually come.
The beauty of Bruno is that he's not system reliant, or reliant on others. Even when coming from those wider areas, he's able to influence the game. For me, I think the problem arises when, for example, Bruno drifts to the left and Rashford doesn't move infield to occupy the space Bruno has left. Or McTominay and Fred don't push forward either.
That happens too often, and we find our attacks are easily nullified because we have no space to work with.
