Juventus defeated Napoli 2-0 at the Allianz Stadium on Sunday evening, and the match was decided not by the balance of ninety minutes but by a concentrated sequence between the 70th and 87th — a period in which the home side scored twice, Napoli lost a man, and Massimiliano Allegri's team ran out of answers to questions they had spent the first hour asking.

The opener arrived at 70', scored by Juventus midfielder Kerim-Sam Alajbegović, assisted by Edon Zhegrova, who had entered from the bench at 59'. That substitution — Zhegrova on for Randal Kolo Muani — proved the hinge of the match. Alajbegović's goal broke a scoreless stalemate that had held through a first half notable mainly for its card count: Juventus collected two yellows before the 21st minute, Douglas Luiz at 16' and Jhon Lucumí at 20', and both sides made changes at the interval — Napoli sending on Amir Rrahmani and Billy Gilmour, Juventus introducing Federico Gatti — reshaping the game structurally without immediately altering its rhythm.

What followed the opener was the moment that sealed it. One minute after scoring, at 71', Alajbegović was booked — and at 72' Luciano Spalletti's Juventus withdrew him immediately, sending Jeremie Boga into the match alongside Lloyd Kelly, who replaced the already-cautioned Lucumí. Then, at 75', Napoli defender Luca Marianucci — who had already been carded at 38' — received his second yellow and was sent off. The numerical advantage was immediate in its effect: Boga, fresh from the bench, converted the second goal at 87', assisted by Andrea Cambiaso, who had entered at 82'. From 0-0 at the 69th minute to 2-0 with ten minutes remaining, the match's entire outcome was written in less than a quarter of an hour.

Boga is the key individual here. Jeremie Boga, Juventus's wide forward, came on with the score already 1-0 and Napoli reduced to ten men, and he converted the chance that made the result safe. His goal was not merely opportunistic — it was the product of a substitution chain that Spalletti managed with precision, and Boga's finish ensured there was no route back for Allegri's side.

Napoli's evening unravelled through a combination of misfortune and discipline failure that they cannot entirely separate. Marianucci's double booking — the first at 38', the second at 75' — left Allegri's team chasing the game with ten men at the worst possible moment, one goal down and the clock running. The red card did not cause the first goal, but it made the second inevitable. Napoli had arrived at the Allianz Stadium with genuine attacking threat — their last five matches before this fixture produced seventeen goals — and Lucca and Noa Lang were available to cause problems. That potential was never converted into the scoreline, and the dismissal ensured it never would be.

Juventus came into this fixture having taken just three points from their last three matches before tonight, with two defeats and five goals conceded in that window. The 2-0 win shifts that recent-form picture considerably: across their last three matches including this result, the Bianconeri now show two wins and one defeat, with four goals scored and two conceded. Napoli, whose last five matches before this game had yielded eight points and eleven goals, now find their five-match form reading two wins, one draw, and two defeats — a flattening of a sequence that had looked more promising a fortnight ago.

A month from now, this match will be remembered as the night a ten-minute passage of play — one goal, one red card, one more goal — turned a tight, goalless contest into a comfortable Juventus win that their recent form had given no particular reason to expect.
