Aside from being far more incisive in posession, the big difference with this midfield is that they compete for and win a lot more 2nd balls.
They're also far more intelligent in terms of shape and positioning. Wintle today did the Gunnarsson role to perfection. I may be being a little harsh here but to me it didn't seem a coincidence that the two times we did get sliced apart was when Vaulks came on.
