How it will be...
The contest might hinge entirely on the dark arts of penalty-box grappling. You should watch for Mehdi Taremi drifting into the inside-left channel, expertly feeling for contact to buy cheap fouls. On the other side, Chris Wood will be launching his battered frame at every cross, testing the structural integrity of the Iranian centre-backs.
A sudden collapse remains the wildcard in this gritty script. Should Iran abandon their strict two-pass exit strategy, they might sink into a panicked, frantic retreat. Yet, if they hold their nerve, their superior set-piece craft should eventually puncture the Kiwi hull. It promises to be an ugly, fascinating study in pure survival.
