Yeah it would work a lot better with Lookman and Bernard either side I reckon. Both want to hover inside as oppose to hugging the touchline.The problem is we played it as a 5-4-1 with Walcott glued to the touchline so Richarlison was left isolated in the same way he is in a 4-2-3-1. The formation needs the correct players or at least instructions for it to work properly.
Also it would mean Walcott doesn't start which is always a good thing.
