I think we'll see a 4-4-2 as well. With O'Brien and Rose, we actually have the personnel to do it for the first time this season. Plus we have an actual winger and two decent forwards available. Wing backs very rarely works in my opinion. Against a good team, it ends up being a flat back 5 with no outlet.
I really hope he does the right thing and drops Stead to the bench, assuming Hemmings is fit.
