Arsenal's patient build-up and Liverpool's first-wave pressure meet at the edge of the visitors' midfield. Both teams can score from the ball immediately after an attack appears to have ended. Arsenal's restarts and Liverpool's quick front line make the second contact especially important. The match should be decided by which side turns that contact into a clean box ball.
Rice and Odegaard can pass through pressure, but Liverpool have Wirtz, Barcola and Isak to use a regain before Arsenal reset. Barcola supplied Isak in Liverpool's recent league win, and Wirtz and Mac Allister played cup minutes rather than becoming new absences. Saliba and Saka are current Arsenal absences; Madueke's next-session fitness was still unsettled in the pre-match reports. The projected lineups are estimates, but Liverpool's league attacking roles have recent playing time behind them.
Liverpool should press the first Arsenal pass and release its runners quickly. Arsenal can build long spells and use Gabriel on restarts, so the decisive stretch is Liverpool's next direct receipt after clearing or winning the ball. That's why I'm siding with Liverpool to take the result.
