In modern football analysis, few metrics spark as much debate as Expected Goals (xG). Designed to measure the quality of chances a player gets, xG offers a baseline for how many goals a player should score. But football, as always, refuses to follow a script.
This season in the Premier League, the gap between expectation and reality has created clear winners and losers. Some players are finishing at extraordinary levels, turning half-chances into goals. Others, despite getting into great positions, simply can’t convert.
At the centre of it all is one standout name.
Antoine Semenyo: The Ultimate Overperformer
Antoine Semenyo has emerged as the league’s most clinical finisher this season—at least relative to expectation. With 16 goals from just 10.15 xG, he’s outperforming his expected tally by a remarkable +5.85.
That’s not just good—it’s elite. Overperformance at this level usually suggests a combination of confidence, sharp decision-making, and perhaps a bit of good fortune. Semenyo is consistently converting chances that, statistically, are less likely to result in goals.
Whether it’s precise finishing, composure under pressure, or simply being in the right form at the right time, his numbers place him firmly at the top of the overperformance charts.
The Chasing Pack: Clinical and Confident
Semenyo may lead the way, but he’s not alone in defying the numbers. Several players are enjoying seasons where everything they touch seems to find the back of the net.
Harry Wilson sits second, with 10 goals from 5.12 xG (+4.88). That’s nearly double his expected return—an indication of outstanding efficiency.
Midfielders feature prominently too. Bruno Guimarães (+4.18) and Casemiro (+3.87) are not traditional goal scorers, making their overperformance even more notable. Their ability to convert limited chances highlights how valuable midfield contributions can be.
Further down the list, players like Kiernan Dewsbury-Hall (+3.57), Junior Kroupi (+3.43), and Richarlison (+3.43) continue the trend of efficient finishing.
Creative attackers such as Eberechi Eze (+3.25) and Jaidon Anthony (+2.69) round out the group, alongside an unexpected defensive presence in Cristian Romero (+2.69), whose contributions from set pieces have boosted his numbers.
Together, these players show that clinical finishing isn’t limited to strikers—it can come from anywhere on the pitch.
What Drives Overperformance?
When players significantly outperform their xG, it raises an important question: is it skill or luck?
The answer is usually a mix of both. Elite finishers can consistently beat xG models by choosing better shot placement, reacting quicker, or maintaining composure in high-pressure moments. However, sustaining large overperformance over long periods is rare.
For players like Antoine Semenyo, the challenge will be maintaining this level. History suggests regression is likely—but that doesn’t diminish how impressive this current run has been.
Kevin Schade: The Other Side of the Coin
While some players are thriving, others are enduring the opposite experience. Kevin Schade stands out as the league’s biggest underperformer.
With 7 goals from 11.05 xG, Schade is underperforming by -4.05—the largest negative gap in the league. Simply put, he’s getting into the right positions but failing to convert at the expected rate.
This makes him the clearest outlier on the other end of the spectrum.
A Struggle for Efficiency: The Underperformers
Schade isn’t alone in his frustrations. Several players are experiencing difficult seasons in front of goal.
David Brooks has scored just once from 4.91 xG (-3.91), while Yerson Mosquera finds himself deep in negative territory (-3.70), highlighting how defensive players can also struggle to convert rare chances.
Strikers like Jean-Philippe Mateta (-3.16) and Dominic Calvert-Lewin (-2.90) are particularly affected, as their primary role is to score. When chances go begging, the spotlight intensifies.
Elsewhere, players such as Riccardo Calafiori, Jefferson Lerma, and Pascal Struijk show how underperformance can affect defenders and midfielders too.
Young attackers like Liam Delap and Amad Diallo round out the list, each struggling to turn promising positions into goals.
Why Underperformance Happens
Unlike overperformance, which can sometimes be attributed to confidence and sharp finishing, underperformance often points to issues like poor shot selection, hesitation, or simply a lack of composure.
However, it’s important not to overreact. xG suggests that players like Kevin Schade are doing many things right—namely, getting into dangerous positions. Finishing slumps can be temporary, and regression toward the mean often works both ways.
The Bigger Picture: Regression and Reality
The beauty of xG lies in its ability to highlight trends beneath the surface. Over time, most players tend to regress toward their expected numbers. That means today’s overperformers may cool off, while underperformers could rebound.
For fans and analysts alike, these numbers offer insight into what might come next. Will Antoine Semenyo sustain his remarkable efficiency? Can Kevin Schade turn his chances into goals?
Conclusion: Football Beyond the Numbers
Ultimately, xG is a tool—not a verdict. It helps explain performance, but it doesn’t define it. Players still decide matches with moments of brilliance, instinct, and emotion that no model can fully capture.
This season’s biggest xG outliers remind us of that balance. Between expectation and execution lies the unpredictable essence of football—and that’s exactly what makes it so compelling.
