Inter beat Monza 4-1 at San Siro on Saturday, and the margin was built in a fifteen-minute corridor between the 48th and 63rd minutes during which Cristian Chivu's side scored three times without reply, turning a match that had been briefly levelled into something considerably more comfortable.
The opening exchanges were controlled by Inter, and Hakan Çalhanoğlu — the Nerazzurri midfielder — put them ahead in the sixth minute, finishing from a move initiated by Andy Diouf. The lead lasted twenty-three minutes. Monza forward Gustavo Varela equalised in the 29th minute, assisted by Mathis Mout, and for a spell Ivan Juric's side looked capable of sustaining the disruption. They could not. Çalhanoğlu collected a yellow card in first-half stoppage time, joining Inter forward Lautaro Martínez, who had been booked in the 34th minute, and both were withdrawn in the 54th minute — Martínez replaced by Ange-Yoan Bonny, Çalhanoğlu by Petar Sučić. The reasons for the double substitution are not stated in the available record, but the timing, coinciding precisely with the bookings, is notable.
Whatever Chivu communicated at the break, the effect was immediate. Inter midfielder Piotr Zielinski scored in the 48th minute to restore the lead, and within seven minutes the match was effectively over. Francesco Pio Esposito, Inter's forward, added a third in the 55th — assisted by Diouf, his second contribution of the afternoon — and Yann Bisseck made it four in the 63rd, finishing from an assist by Esposito. Three goals in fifteen second-half minutes, each one building on the last, with Diouf and Esposito functioning as the connective tissue of the move set.
The key individual across the ninety minutes was Diouf. The Inter midfielder finished with a match rating of 8.2 — wait, that belongs to Çalhanoğlu. Diouf's rating was 7.6, but his two assists across 59 minutes of play made him the most consequential single contributor to the scoreline. The first set up the opener in the sixth minute; the second, in the 55th, led directly to Esposito's goal and the passage that closed the contest. Çalhanoğlu, rated 8.2 in 54 minutes, scored before his early exit; Zielinski and Esposito each rated 7.7 in their 59 minutes. The collective quality of Inter's midfield output was the structural reason for the result.
Monza's problem was not simply the scoreline but the shape of it. Varela's equaliser — rated 7.3 on the day, the best performer in Juric's squad — gave them a platform they could not hold. Their defensive unit, with Ricardo Mangas, Adam Bakoune, and Samuele Birindelli each rated 6.5 or 6.6, was functional without being resistant, and the second-half substitutions — three changes in the 70th minute, bringing on Omari Forson, Nicolas Galazzi, and Patrick Cutrone — came after the damage was already done. A yellow card for Eddy Kouadio in the 69th and a yellow card for Lorenzo Lucchesi in the 84th, who was then substituted, added disciplinary fragility to a performance that had already conceded structural control.
Inter begin the Serie A season with three points, four goals scored, and one conceded. Monza, opening on zero points with a four-goal deficit in their first league outing, carry the weight of a difficult start. The Coppa Italia win over Avellino earlier in August offered Juric's squad some confidence, but the gap between that competition and a Serie A opener at San Siro was made visible across sixty-three minutes of football.
What this match establishes is that Inter's midfield depth — the capacity to lose two starters at half-time and still score three times in the second half — is the most significant fact about this team heading into the weeks ahead.
