Lazio vs AC Milan Lineups September 2026 – Maintaining their perfect league record this season, Lazio will welcome unbeaten AC Milan to their home ground on matchday four of the 2026/2027 Serie A season.

The match is scheduled to take place at Stadio Olimpico on Saturday, September 12, 2026, at 6:00 PM local time.

Since being eliminated from the cup competition, the Biancocelesti have collected the maximum nine points in Serie A, two points ahead of Milan.

Now, before this match begins, let us take a look at Mansion Sports' prediction for the Lazio vs AC Milan lineups in September 2026 below!

Conditions of Both Teams Ahead of the Match

Lazio

Lazio continued their perfect start to the league on Monday evening by coming from behind to defeat Udinese 2-1 thanks to goals from Davide Frattesi and Albert Gudmundsson.

After Frattesi scored his third goal in three matches while captain Mattia Zaccagni had hit the post, debutant Gudmundsson completed the comeback with his 88th-minute header.

As a result, the Biancocelesti have won their first three Serie A matches for only the third time in their history, as well as for the first time since 2012.

New manager Gennaro Gattuso came under immediate scrutiny last month when Lazio were eliminated from the Coppa Italia by Mantova, but their response since then has clearly strengthened his position.

Although the former Italy national team manager previously played for and coached Milan, making 335 league appearances and taking charge from the touchline 62 times as a coach, his loyalties will be different this weekend.

Ahead of Saturday's match, Lazio have won three of their last four meetings in all competitions, and their recent results suggest that they have an opportunity to extend that trend.

AC Milan

Milan actually lost twice to Lazio at the Olimpico last season, suffering 1-0 defeats in both the league and cup competitions. However, this visit comes after a summer of significant changes for the red-and-black side from Italy's second-largest city.

Ruben Amorim took over from Max Allegri, and his team came close to matching Lazio's nine points from their first three matches. However, they dropped two points during stoppage time last week.

Although Alphadjo Cisse's excellent finish gave the Rossoneri a valuable lead to protect against Juventus, the hosts managed to earn a deserved draw through Federico Gatti's powerful header.

That result followed two consecutive victories at the beginning of the Amorim era, against city rivals Juventus, Torino, and newly promoted Venezia respectively. As a result, they remain unbeaten at least.

After suffering a collapse toward the end of his second spell with Allegri, Milan must go through this season without Champions League football, while their Europa League campaign will begin next week.

That journey will begin with an attractive home match against Benfica, but before that, they must first travel to Rome.

Lazio vs AC Milan Lineups September 2026

Lazio (4-3-3)

Regarding Lazio's squad condition, there were concerns over Andrea Pinamonti's fitness, who made his first start in Udine, after the new striker was forced off with an ankle injury on Monday.

Gudmundsson has just arrived as a versatile forward, while Tijjani Noslin can also provide cover. However, Pinamonti has returned to training and should be declared fit to play.

However, the hosts are still without two defenders, Patric and Adam Marusic, as well as two midfielders, Nicolo Rovella and Danilo Cataldi. Fisayo Dele-Bashiru could also miss out.

On the more positive side, Gattuso has gained an additional defensive option after Lazio signed Diogo Leite as a free agent.

AC Milan (3-4-2-1)

Meanwhile, regarding AC Milan's squad condition, the only confirmed absentee should be Mattia Gabbia, while former Lazio defender Mario Gila is expected to continue playing despite an ongoing knee problem that has been troubling him.

If Gila is able to tolerate the pain and continue playing, Amorim is likely to retain the same back three. However, the Rossoneri manager has been more inclined to rotate in the attacking areas.

Although new signing Omari Hutchinson will look to earn his first appearance, several other players are also competing to partner Goncalo Ramos in attack.

After scoring against Torino and Juventus, Cisse has given a strong reason to be included in the starting lineup. Meanwhile, Alexis Saelemaekers, Ruben Loftus-Cheek, and Christian Pulisic are also hoping to start.

The meeting between Lazio and AC Milan is an interesting encounter as both teams arrive with positive momentum.

Lazio want to maintain their perfect record in Serie A, while Milan are looking to preserve their unbeaten status while securing the maximum result at Stadio Olimpico.
