Inter clinched a 3-0 victory against Cagliari at San Siro on Friday evening, a result forged in a crucial four-minute spell between the 52nd and 56th minutes that transformed a tense, goalless affair into a comfortable rout. The Nerazzurri, at home under Inter coach Cristian Chivu, bagged two goals in that period and netted a third deep into stoppage time to secure their third successive league win in Serie A.

The first half was largely uneventful save for two yellow cards — one for each side, both issued within two minutes of each other in the 23rd and 25th — hinting at a cagey contest, fought more in the midfield battle than through flowing football. Cagliari coach Davide Nicola's side defended compactly, stifling Inter's build-up play and limiting their space to breathe. The Nerazzurri dominated possession but lacked penetration, and the teams went in level at the break.

The second half, however, was a completely different story. Inter broke the deadlock in the 52nd minute, and before Cagliari could reorganise, they struck again in the 56th. Two goals in four minutes is less a collapse, more a systemic breakdown: Nicola's men had maintained their defensive shape for 52 minutes and then shipped two goals before the coaching staff could even contemplate a change. The dual substitution that followed in the 57th minute — two players off, two on — was the correct response, but it came a minute too late to avert the damage. Inter's third, netted in the 90th minute after a series of changes from both benches, simply rubber-stamped an already foregone conclusion.

Inter midfielder Nicolo Barella was the standout performer on the pitch, finishing with a rating of 7.7 — the sole player in either starting XI to surpass that mark. He registered no goals or assists in the 39 minutes of action captured, but a rating of 7.7 in a match where Inter dominated the second half almost completely highlights an influence not fully captured by mere statistics: the quality of his intelligent positioning between the lines, the rapidity with which he recycled the ball, and the relentless pressing he applied when Cagliari attempted to play out from the back. Inter's next rated performers — Inter midfielder Hakan Calhanoglu and Inter defender Federico Dimarco — each scored 7.0, with a host of other Nerazzurri stars posting 6.9s, pointing to a strong collective effort rather than individual brilliance, which is in line with the team ethos Chivu has cultivated during this recent run of form.

Cagliari's evening was ultimately shaped by a form guide that rendered this result largely predictable. Davide Nicola's men arrived at San Siro having secured only one win from their preceding four league outings — a narrow 1-0 home victory against Cremonese — and having shipped seven goals in the three games prior to that. Against Inter, they managed to frustrate the hosts for 52 minutes, no mean feat, but their attacking output was virtually non-existent. The head-to-head record between these clubs now stands at two Inter victories from two meetings, with the Sardinians failing to find the net in either fixture, which suggests a fundamental tactical mismatch rather than a mere run of bad luck.

Inter's recent form now boasts three wins from three outings: a thrilling 4-3 away at Como, a commanding 5-2 triumph against AS Roma at home, and now this. The Nerazzurri have plundered a remarkable twelve goals across those three encounters. For Cagliari, the league position looks far more precarious: four losses in five league games, with the only victory coming against a Cremonese outfit languishing in the same lower echelons of the table. The gap between Nicola's men and the relegation zone will undoubtedly have shrunk, and the upcoming fixtures will carry even greater significance.

Inter's latest triumph extends a formidable sequence that has dramatically altered their late-season trajectory. Three successive wins, a dozen goals bagged, and a defensive solidity that has seen them concede just once in their last two league outings – that solitary goal coming in the draw at Fiorentina – provides Chivu's charges with the kind of irresistible momentum that often proves decisive in title races.

A month from now, this match will be recalled not for its inherent drama, but for its clinical efficiency: Inter took 52 minutes to prise open Cagliari's stubborn defence, and a further four to put the result beyond any doubt.
