Caldwell is expected to stick with his trusted 3-5-2, with Llyton Chapman, Morgan Fox and Jon Mellish forming the back three, flanked by wing-backs Connor Barrett and Fraser Murray. That shape gives Wigan numbers in midfield and allows them to overload the wide areas — perfect for stretching a side that likes to defend narrow. The double pivot will be key, screening the back three and launching quick transitions through the half-spaces. Leyton Orient, predicted to line up in a 4-2-3-1, will look to stay compact and frustrate, with the attacking midfielder pulling the strings between the lines.

The battle will be won in midfield. Wigan’s extra man there should give them control, but Orient’s two holding midfielders are disciplined and will make life difficult. The wing-back duel is where Wigan can really hurt them — if Barrett and Murray get joy early, Orient’s full-backs will be dragged wide, opening up the centre for Wigan’s runners. Set pieces could also be a factor, with Wigan’s height advantage from the back three a real threat at both ends. Expect Wigan to dominate possession, but Orient will be dangerous on the counter, especially if they can spring their wide players in behind.
