We don't have confirmed lineups or formations from the brief, but we can paint a picture from what we know. Sheffield United under their current setup are expected to line up in a solid, organised shape — likely a 3-5-2 or a 4-2-3-1, built on a double pivot that shields the defence and lets the wing-backs bomb forward. Bramall Lane is a cauldron, and the Blades will look to press high, force errors, and feed off the crowd's energy.

Birmingham, meanwhile, are likely to set up in a compact mid-block, maybe a 4-4-2 or a 4-3-3, designed to frustrate and hit on the break. Their draw with Barcelona showed they can sit deep and absorb pressure, then spring forward with pace. The midfield battle will be a dogfight — second balls, loose tackles, and who wants it more. Sheffield United will try to knife through the lines with quick passing; Birmingham will look to stay narrow and make it ugly.

The key duel will be out wide. If the Blades' wing-backs get space, they'll cause chaos. If Birmingham's wide men track back and double up, they can nullify that threat. Set pieces will also be huge — both teams have physical units, and a dead-ball moment could decide a tight game. Expect a cagey opening, then the game opening up as the crowd demands more.
