Insights from Xinrui Chen & Yufei Tang’s Research
I have been doing a deep dive into the statistical side of the game for the last year, and I came across this paper that I had to write about. The Messi vs. Ronaldo debate has fueled football arguments for over a decade, but this study, “Judging Messi’s and Ronaldo’s Scoring Ability in Different Situations According to the Model” by Xinrui Chen (University of California Davis) and Yufei Tang (Stony Brook University), cuts through the noise with real numbers. It breaks down exactly how and where these two legends find the back of the net, using expected goals (xG) models and in-depth statistical analysis.
If you’re serious about becoming a better finisher, this study is a must-read. It doesn’t just compare goal totals, it analyzes efficiency, shot selection, and game intelligence to determine why Messi and Ronaldo score at elite levels.
Breaking Down the Numbers
One of the biggest takeaways from the study is Messi’s dominance in expected goal efficiency. According to the data, Messi consistently outperforms his xG, meaning he scores more goals than an average player would from the same opportunities. Ronaldo, on the other hand, relies on volume, taking more shots and positioning himself to create more chances.
Messi’s Finishing Efficiency
- Messi’s xG per shot: 0.117 (11.7% probability of scoring per shot).
- Actual goals per shot: Higher than expected, meaning he converts low-percentage chances more often than other players.
- His ability to create and convert difficult chances sets him apart from traditional strikers.
Ronaldo’s Strengths in Volume and Variety
- Ronaldo’s xG per shot: 0.104, slightly lower than Messi’s.
- He compensates with higher shot volume, attempting more shots per match than Messi.
- Elite in open play and set pieces, showing versatility in different scoring situations.
Where They Score From
The study also provides a detailed breakdown of goal locations and finishing styles.
- Messi thrives in tight, technical finishes, often cutting inside from the right onto his left foot.
- Ronaldo is more adaptable, scoring from headers, long-range shots, and poacher positions inside the box.
Shot Zones and Finishing Trends
- Messi scores a higher percentage of goals from outside the box, showcasing his ability to create shooting angles and strike from distance.
- Ronaldo is dominant inside the box, leveraging movement, positioning, and aerial ability to capitalize on high-xG chances.
Game Situations: Who Delivers Under Pressure?
Another key aspect of the study is analyzing when Messi and Ronaldo score their goals.
- Ronaldo excels in the second half of matches, particularly after the 60th minute, where his fitness and mentality shine through.
- Messi is more balanced, scoring at consistent rates throughout the match, but particularly dangerous in early phases of play when defenses are still adjusting.
This confirms what we’ve seen throughout their careers, Ronaldo thrives in clutch moments, while Messi is a constant, efficient goal threat at all times.
What This Means for Players Trying to Improve Their Finishing
- Understand xG: If you’re consistently taking low-xG shots without elite finishing ability, you’re making life harder for yourself. Learn which shots are worth taking and which ones to pass up.
- Shot selection matters: If you want to increase your goal tally, study where your goals come from and find ways to improve high-percentage chances.
- Positioning and movement are key: Ronaldo has built his career on being in the right place at the right time. Becoming a better finisher isn’t just about striking ability, it’s about knowing where to be when it counts.
- Game intelligence separates good finishers from great ones: Messi’s ability to create space and manipulate defenders gives him better quality chances. If you’re not thinking two steps ahead, you’re relying too much on reaction rather than control.
Final Thoughts
This study by Xinrui Chen and Yufei Tang reinforces what makes Messi and Ronaldo two of the greatest goal-scorers in history, but for completely different reasons.
- Messi’s efficiency, technique, and creativity make him a lethal finisher from areas most players wouldn’t even attempt to shoot from.
- Ronaldo’s volume, athleticism, and positioning allow him to be a constant goal-scoring threat in multiple ways.
For players looking to improve, there’s no single “best” way to score goals, but there is a best way for you. Are you a creator like Messi, who finds angles and exploits space? Or are you a finisher like Ronaldo, who maximizes every chance that comes his way?
The key takeaway? Study your own game the way this study analyzed these two. Track your xG, analyze your shot locations, and refine your strengths. If you’re serious about scoring more goals, stop relying on talent alone, get intentional with your finishing.
