Juventus forward Randal Kolo Muani extended his goalless run in Serie A to four matches on Sunday as the Bianconeri surrendered a lead to lose 3-2 against Sassuolo, with Vasilije Adzic's goal in the final moments completing a collapse that leaves Luciano Spalletti's side eighth in the table with seven points from four games.

The defeat sharpens a question that has hung over Juventus since the summer: whether Kolo Muani, signed from PSG, can produce the volume of goals a club of this stature demands. Walter Zenga has said publicly that Juventus do not have a striker capable of reaching fifteen goals in a season — and through four Serie A matches, the 27-year-old has done nothing to challenge that assessment. One assist is his only registered contribution. His average rating of 5.96 across those four appearances sits below the threshold that separates a player finding his feet from one who is genuinely struggling.

The context around him is not straightforward. Juventus were forced into changes for the Sassuolo fixture, fielding Teun Koopmeiners, Nico Gonzalez, and Kerim Alajbegovic in support of Kolo Muani — a lineup shaped by an injury crisis severe enough that the club started no Italian outfield players for the first time in their history. Depleted squads rarely flatter their centre-forwards, and Kolo Muani is no exception. But structural excuses only stretch so far when the team is conceding late and the striker's contribution column reads zero goals.

Edon Zhegrova scored twice for Juventus in the defeat, which at least demonstrates that attacking threat exists somewhere in the squad. The problem is that Zhegrova's output came from wide, not from the position where the goals are most needed. Kolo Muani's AI overall of 63 out of 100, with a potential of 68, suggests a player operating near his ceiling rather than one still ascending toward it — a reading that makes the current blank run harder to dismiss as a slow start.

Spalletti's Juventus have scored six times in four league matches, a rate that is functional but not dominant for a side with European ambitions. If Kolo Muani cannot convert chances into goals as the fixture list grows more demanding, the arithmetic of the season will become uncomfortable quickly.
