Khusanov is better than Dias with the ball, not because he's more technical, more skilled, or has better vision. No, it's simply because he doesn't think he's Beckenbauer. He's aware of what he can do and what he can't. He's old-school; he plays simply and doesn't attempt complicated things.
When Dias tries to advance slowly towards the opponent with the ball, and at the last second, when the passing angle narrows, he makes a poor pass to Ake or Ait Nouri and embarrasses them, then backpedals. Khusanov makes a simple pass. He doesn't attempt things he's not capable of. That's why he's better. I've seen about twenty of his matches with Lens, when his team was creating a sensation in the French Ligue 1 and the Champions League.
Let's give him 5 matches in a row, and we'll see if he doesn't win everyone over.
