Mantova arrived at the Olimpico as guests from Serie B and left with a 0-2 victory that Lazio, the hosts, had no coherent answer to across ninety minutes. The margin was built in the final quarter of the match, but the conditions for it were set long before Francesco Ruocco's name went on the scoresheet.
The first decisive passage came not from a goal but from the triple substitution Mantova coach Francesco Modesto made at the 56th minute, withdrawing Rareș Ilie, Bodin Tomašević — who had already picked up a yellow card — and Lorenzo Ignacchiti's eventual replacement, bringing on Davide Bragantini among others. The changes sharpened Mantova's attacking threat precisely when Lazio's own midfield was being disrupted: Fisayo Dele-Bashiru, the Lazio midfielder, collected a yellow card at the same minute, and Maurizio Sarri's side would not respond with their own substitutions until the 64th minute. That gap in reactive management mattered.
Ruocco's opener arrived at the 75th minute, assisted by Bragantini — one of the players Modesto had introduced nineteen minutes earlier. The goal came with Lazio already having made three substitutions of their own, including Davide Frattesi and Petar Ratkov entering in the 71st minute in an attempt to alter the game's direction. It did not. Lazio pushed forward, Nicolò Rovella was withdrawn at the 79th minute, and at the 90th minute an unnamed Mantova player, assisted by substitute David Wieser, confirmed the result. Two goals, both from the second half, both products of Mantova's bench.
Bragantini is the individual who shaped this result most directly. Introduced at the 56th minute, the Mantova forward provided the assist for Ruocco's lead-taking goal and was the connective tissue in the move that broke the match open. His involvement illustrates a recurring pattern in Coppa Italia upsets: a second-tier squad with a specific tactical adjustment, applied at the right moment, can expose a top-flight side that has not yet found its competitive rhythm.
Lazio's evening was a catalogue of what a team in uncertain form looks like when pressed. Sarri's side collected three yellow cards — Rovella, Dele-Bashiru, and Matteo Cancellieri, the last of whom was booked in the 79th minute as he was being substituted off — and made five substitutions without altering the match's direction. The eleven Sarri started were not without quality on paper: Zaccagni, Dia, and Dele-Bashiru in the attacking and midfield zones represent genuine Serie A currency. But the team produced no goals against a Serie B opponent, and the defensive structure — four recognised defenders in Doekhi, Pedraza, Provstgaard, and Marusic — conceded twice in the final twenty minutes. The structural problems were not corrected by the changes made.
Lazio's form across their last five matches, a window that spans both Serie A and Coppa Italia, reads one win, four defeats, with ten goals conceded and only two scored. The last three matches tell a similar story: one win, two losses, five goals against. The single win in that run came against Pisa in May. This Coppa Italia exit does not change the arithmetic of those numbers, but it confirms that whatever Sarri's side is building toward, it has not yet taken shape. Mantova, for their part, have won two of their last three, both coming in this Coppa Italia campaign, and Modesto's team demonstrated that their Serie B experience has not dulled their capacity to organise and execute against higher-division opposition.
A month from now, this result will be remembered as the evening Mantova walked into the Olimpico, made the right substitutions at the right moment, and exposed a Lazio side that could not find the game when it mattered.
