I think the most likely incoming players for us will be a pair of central midfielders who can press hard and provide the same kind of forward passing as Bentaleb and Mason. Some extra defensive abilities would also be great, but really, the problem we have is that the system needs two overlapping fullbacks, and two midfielders who press hard and get the ball forward quickly. We only have one suitable right back, and one pair of midfielders which can do this, it seems. And without them, the whole crazy system falls to pieces.
