After looking at the line up - I’ve changed my mind from 4-0 to 6-1. It will be history repeating itself. But in reverse - if yer know what I mean.
Can only assume that Struber feels like he has enough defensive options to shift things around, with Williams, Andersen, Helik and Sollbauer on the pitch. Personally, I prefer to see Williams at the left of that back three, he was growing nicely into the role, to the point where he looks the least likely to make a mistake.
