I'd be a bit surprised if we play 4-4-2. We've only done that once, v Newcastle, and they played 442 too. Wigan will have 3 in the midfield, so I'd expect us to match that.
I reckon it just means shunting Gabby wide left from last week's team.
Pretty happy with that side personally, but we'll need Ireland and Gabby to be athletic and support Bent a la second half last Sunday. If they don't we'll struggle to connect Bent to the rest of the side
