I know he won't do it, but I'd like to see Willian on for Costa and Hazard as a false nine.
Anyway, I wasn't talking about substitutions. I meant playing a bit wider, more diagonal balls, maybe Azpi and Cahill overlapping with Moses and Alonso? There is no room at all through the middle.
Also, we need to try to isolate and keep running at their players with yellow cards.
