Roma’s 2–0 victory over Genoa was built on clinical moments and a disciplined defensive performance rather than a succession of clear-cut chances.
The Understat figures supplied for the match put the Giallorossi on 1.41 expected goals from 11 shots, compared with Genoa’s 0.51 from nine attempts. Santiago Castro’s outstanding opener broke the deadlock before Emanuele Lulli converted Roma’s highest-quality chance to secure the points.
Expected goals measure the estimated likelihood of a shot becoming a goal. They offer useful context on chance quality, although different models produce different figures and cannot capture every aspect of a performance.
Castro Converts a Low-Probability Chance
Castro’s opener carried a value of just 0.08 xG, underlining the difficulty of the finish that put Roma ahead.
Lulli’s goal, by contrast, was valued at 0.56 xG, accounting for almost 40% of Roma’s total.
Only two other Roma attempts exceeded 0.10 xG: Rodrigo Mora’s opportunity in the 31st minute, worth 0.30, and another Castro effort valued at 0.14, which came with the hosts already leading 2–0.
Roma averaged approximately 0.13 xG per shot. Those figures suggest a limited number of high-quality openings, with Castro’s individual brilliance proving particularly important in unlocking the match.
According to the supplied analysis, it was Roma’s second-lowest attacking xG total of the league season, ahead only of the draw at Como.
Roma Keep Genoa’s Chances to a Minimum
The defensive numbers were more encouraging for Gian Piero Gasperini.
Although Genoa registered nine shots, their combined value of 0.51 xG reflects the low quality of the opportunities Roma allowed. Junior Messias’ attempt in the 58th minute was the visitors’ only shot above 0.10 xG, at 0.11.
It was Roma’s second-best defensive performance of the league campaign by expected goals conceded. Only the opening match against Fiorentina, when they allowed 0.29 xG, produced a lower total.
The contrast is significant: Genoa managed only two fewer shots than Roma, but the hosts created substantially better opportunities.
Castro Opens His Serie A Account
Castro’s first league goal takes him to one goal from 1.39 xG this season, leaving him slightly below his expected total.
The supplied figures show a similar pattern across his previous two campaigns: seven goals from 8.30 xG last season and eight from 8.54 xG the season before.
Those totals provide context rather than a definitive judgment on his finishing, particularly given this season’s limited sample. Against Genoa, his contribution was decisive: a difficult chance converted into the breakthrough Roma needed.
For Gasperini, the result offered a valuable combination—a moment of attacking quality and a defensive display that gave Genoa little opportunity to respond.
