ROME (Interstat) — A solitary first-half strike from Gustav Isaksen propelled Lazio to a 1-0 victory over AC Milan in a tightly contested Serie A match at Stadio Olimpico on Sunday, March 15, 2026.

The result handed Lazio a winning start to their domestic campaign while leaving Milan searching for answers after a season-opening defeat. The match, played before a capacity crowd in the Italian capital, largely followed a script of defensive discipline and limited clear chances, with Isaksen’s moment of quality proving decisive.

The game’s only goal arrived in the 26th minute, stemming from an unexpected source. Lazio goalkeeper Edoardo Motta initiated the play with a long, driven goal kick that found substitute defender Pervis Estupiñán advancing on the left flank. Estupiñán, who had entered the match earlier, controlled the pass and immediately drove forward before delivering a low, hard cross into the Milan penalty area. Defender Nuno Tavares, arriving at the far post, deftly redirected the ball across the face of the goal with a first-time touch, leaving Isaksen with a simple tap-in from close range.

The assist for Tavares was a rare offensive contribution, while Motta’s long assist highlighted a proactive performance from the Lazio goalkeeper. The goal underscored a match where defensive players significantly influenced the attacking outcome.

Milan struggled to mount a consistent response throughout the match. Lazio’s organized defensive block, marshaled effectively in the second half, limited the visitors to mostly speculative efforts from distance. The Rossoneri failed to seriously test Motta after the interval, as Lazio comfortably managed their narrow lead.

The match grew increasingly fractious as Milan’s frustration mounted. The second half produced a flurry of yellow cards, with five issued after the 55th minute. Estupiñán was booked for a late challenge in the 55th minute, and remarkably, goal contributor Motta saw a yellow in the 70th minute for time-wasting. Tavares joined them in the book in the 81st minute. The match concluded with a tense finale, as Lazio’s Pedro and Patric both received yellow cards in stoppage time during a series of confrontations.

The final result defied the pre-match projection from Interstat’s game simulator, which had forecast a 1-1 draw. However, it aligned with the analytics firm’s ELO rating system, which gave Lazio an 85.80 percent probability of victory, a figure borne out by the disciplined display from the Roman club.

With the victory, Lazio begins its Serie A season with a perfect record of one win and no losses, also moving its overall record across all competitions to 1-0-0. AC Milan, conversely, starts its campaign with a defeat, holding a record of 0-1-0 both in Serie A and in all competitions. The teams will look to build on these results when the Italian league season continues next weekend.
