These matches should be decided by the first aerial or midfield duel and the pass that follows it. Elversberg and Mainz both have runners who can attack space behind an advanced wide player. Sheffield United and Wrexham can also reach the box through wide service or a second ball. Clean follow-up touches matter more here than raw possession or a recent shot count.
Elversberg can take the second ball through Keidel and move it toward Petkov, Mokwa or a wide runner. Mainz's Becker and Caci offer a sharp reply behind an advanced defender, but coach Urs Fischer has acknowledged gaps in his side's possession structure and rest defence. Günther and Pinckert both played the full cup tie despite later doubtful tags; Mainz are without Kohr, and Amiri's cup absence leaves his receiving role unsettled. Elversberg's home attacks have come from transitions, corners and direct runs, giving them more than one way to answer Mainz's supply. That's why I'm siding with Elversberg to hold their ground.
Sheffield can use Chong and Brereton Díaz to stretch Wrexham's outer defenders, then seek Bamford or a runner on the second contact. Wrexham can go through Moore's first header, O'Hare's next pass and Whiteman's set-piece delivery to Smith or Worrall. The Hyam, Worrall and Doyle back line already played together despite the older Wrexham absence list, while Sheaf has returned to minutes. Sheffield's large Derby shot surge came largely against ten men, and their opponents have still found regular chances. Wrexham's existing forward chain gives them a real answer at full strength. That's why I'm siding with Wrexham to avoid defeat.
