I think not having a powder puff midfield in front of them helped our entire back four and GK tbh mate.
I've swore up and down if you made a dream back four of the last 15 years of Hutton, Cuellar Bougherra, Papic and stuck fucken Halliday, Holt, Zelalem, Ball, Windass, Barton or Kranjcar in front of them they'd get roasted nearly as often.
