Recently, a lot of good players leave the ship, actually. Maybe the rumors about they getting Vidal are true. And, in order to get a new player, they need to sell someone. They're definitely not gonna sell Bale, James, Modric or Kroos. So, Isco is the only quality player who they can sell for a great amount of money. That hypothesis has some sense if you think about it. I mean, that team has lot of quality, but lacks some physical presence, especially in the eyes of someone like Benítez. He's not a manager like Guardiola or Ancelloti.
