The physicality in Madrid and Barca's team is not all that needed since they adopt a completely different style of play. One that we're not capable of reproducing.
The other rather twisted comparison here is the one your making with our insufficient midfield. And Verratti barely has any caps for the senior Italian team, so also that is a huge exaggeration. Verratti simply does not have the infiltrations in him that Khedira, Pogba or Vidal have. He can play as a CM yes, but that would make Pjanic surplus to requirement and we're obviously betting on him... While of course we'll be keeping Marchisio, so yeah if we spend that kind of cash it better be a more apt piece of the jigsaw.
It was nice discussing, but we're running in circles now.
