Gattuso will stick with his trusted 4-3-3. Christos Mandas is locked in goal, with Danilho Doekhi and Oliver Provstgaard patrolling the center of defense — a pairing forced by injuries but one that's gaining chemistry. Adam Marušić and Alfonso Pedraza provide width from full-back. The midfield trio of Davide Frattesi, Nicolò Rovella, and Kenneth Taylor is the engine room — Rovella sits deep, Frattesi bursts forward, Taylor does the dirty work. Up top, Mattia Zaccagni is the creative spark, cutting in from the left, while Boulaye Dia leads the line with his movement and finishing. This is a side that wants to press high, win the ball in dangerous areas, and knife through the lines with quick, vertical passes.

Allegri will likely mirror the 4-3-3, but his approach will be far more pragmatic. With an unprecedented center-back pairing forced by injuries, he'll set up to defend deep, stay compact, and hit on the counter. Genoa will look to frustrate Lazio, slow the tempo, and nick something from a set-piece or a moment of individual brilliance. But this is a team that's been leaking goals — the Bournemouth horror show wasn't a one-off. The double pivot of Rovella and Taylor should dominate the midfield dogfight, and with Frattesi making those late runs into the box, Genoa's makeshift defense will be stretched thin. The wide areas are where Lazio can really hurt them — Zaccagni and the full-backs will overload the flanks, and Genoa's full-backs will be isolated. Set-piece kings? Lazio have the height in Doekhi and Provstgaard to cause chaos from dead balls.
