Gundogan has all the defensive capability of Yaya five years from now.
Pragmatic means maybe playing with two Dm’s. Maybe Fern and Delph or Danilo, Kev playing deep in between them or just in front of them and playing more like a quarter back. Those three with Silva, Stirling/Bernardo, Sane in front with instructions to keep the ball. Even three at the back and wing backs can be played more defensively. You are right in that if the attitude is lacking it doesn’t really matter what formation you play though.
