I don't think Bruno can play there due to the fact that we don't have fast goal-scoring forwards on the flanks who can constantly run behind the defense. Rashford can do it at his best, but Sancho is not even a wing forward in a strict sense. Bruno would be terribly isolated in the middle against stronger and bigger players directly man-marking him.
One of the main advantages of a false 9 is that you can't really man-mark that player. If you man-mark with a CB the false 9 will drag the CB out of position, opening up space for the wingers and runners from midfield.
If you man-mark with a DM all the false 9 needs to do is hog the offside line and you've essentially turned the DM into a 3rd CB. Pegs the opponent back and leaves acres of space for your midfielders to dictate play (perfect for Eriksen).
