Expect Valur to line up in their usual 4-3-3, with pace on the wings and a midfield that can control the tempo. Their full-backs push high, and the front three like to interchange, dragging defenders out of shape. The double pivot in midfield will look to dominate the second balls and feed the half-space runners. KA Akureyri, as the brief suggests, are likely to set up in a 4-2-3-1, sitting a little deeper and looking to hit on the break. Their number ten will try to find pockets between the lines, but they'll need to be clinical because chances will be few. The key battle will be in the middle of the park: Valur's three against Akureyri's two. If Valur can win that dogfight, they'll pin the visitors back and create a steady stream of chances. Set pieces could also be a factor — Valur are dangerous from dead balls, and Akureyri will need to be alert.
