RNfinity | 24-12-2024In the world of football, the adage "form is temporary but class is permanent" holds more significance than ever. As a global phenomenon, football captivates billions, extending far beyond the pitch into various entertainment and business sectors. Statistical analysis has become an integral part of football culture and in match reporting, such as BBC live results, transforming how fans, pundits, and professionals understand the game. Modern football discourse now routinely includes concepts like: These metrics offer deeper insights into player and team performances, enriching the beautiful game with data-driven narratives. Predicting match outcomes has evolved into a sophisticated industry. Betting companies employ complex algorithms, while media outlets frequently report on simulated results and projected league standings generated by advanced predictive models. The football experience now extends far beyond live matches, encompassing: This digital ecosystem has created new avenues for fan engagement and data-driven content creation. As technology advances, we can expect even more sophisticated analytical tools to emerge. Machine learning and AI are likely to play increasingly significant roles in match prediction, player scouting, and tactical analysis, further blurring the lines between traditional football knowledge and data science. Never has the beautiful game been so thoroughly dissected.Predicting Football Wins: Advanced Analytics and Fan Engagement

What is form and what is class?
There is a saying that from is temporary but class is permanent but what is form and what is class, and can they be quantified? Are they two different entities? How to begin to answer this question and what exactly is the question?
Q
uestion; what length of form or previous performance
is the strongest predictor of the outcome of a football match. Might there
be two peaks, perhaps a short-term peak and a longer term peak?
Ok so I needed to get some data. The premier league results
for the previous 20 years are readily obtainable as downloadable CSV file. I
got it from Kaggle.com. free of charge after registering.
I decided to use the average point total for varying lengths
of previous matches for each team, and their opposition. This took a little bit of jiggling of columns around the spreadsheet. I used
the following lengths of previous matches as predictors; 1,3,5,10,20,40,50,60,100 for each side in the match. The longer range of prior matches, may present a slight problem for
teams who were relegated after short stints in the premier league and did not have this amount of prior Premier League matches. I used all
the teams (with missing data leading to an omission of a particular match form the analysis) rather
than selecting only the premier League ever presents for analysis, - Arsenal, Chelsea, Everton, Liverpool,
Man United, Tottenham. This alone is perhaps the ultimate statement of class.
Using binary logistic regression to predict the win, using just two variables each time, whether the match was home or away for that team, and one
of the average point streaks for the 9 periods above. I compared the strength
of each of these models using the R2 statistic for each of the
models. R2 ranges from 0 for completely unpredictable to 1.00 for perfectly
predictable.
The results are shown below. These calculations are based on between 9000 and 12000 matches;
Interpretation of results
So, what does this mean? From the above graph, the single strongest
predictor of match win for a side is the average points tally over the previous 50 games
for that side, a surprisingly long period of time. For the opposing team form, the
findings are similar with predictability plateauing at 60 games. There is a
single peak in both cases. There is no early peak suggesting that recent runs
of form are more likely due to random factors. Off course, there is some additional
information conveyed from the recent run of form but very little. Starting with
all previous form durations combined into one model, together with whether the matches
were played home or away, then sequentially eliminating the factors with little
or no discrimination, the model R2 increase from 0.123 for the 50-game
or 60 game form to 0.191. In this model the form for 40, 60 and 100 games
and the previous game were retained in the model as strong predictors, whilst
3,5, 10 and 20 game form, like the proverbial Accrington Stanley (sorry),
have been eliminated.
This season some big sides have had a drastic downturn in
form, notably Man City and Man United, and the outcome of their recent matches, seem
out of keeping with their longer term performance, however this seems to be the exception.
These result off course are sport specific and premier league specific, but perhaps indicates something about the cohesion of football clubs.
The results from various studies on football team performance highlight the complex interplay of factors that influence a club's success. While these findings are often specific to particular leagues or contexts, they offer valuable insights into the broader dynamics of team cohesion and performance in football. Football clubs often foster a strong sense of identity and tribal allegiance among players and fans alike. This phenomenon can significantly impact team performance: The stability of coaching and support staff plays a crucial role in team performance: Injuries can significantly disrupt team dynamics and performance: Ekstrand, J., van Zoest, W., Grinberg, H., & Waldén, M. (2023). Changes in head staff members in male elite-level football teams are associated with increased hamstring injury burden for that season: the UEFA Elite Club Injury Study. BMJ Open Sport & Exercise Medicine, 9(4), e001640. Several factors contribute to team cohesion in football: While the specific impacts may vary across leagues and cultures, the overall evidence suggests that team cohesion, stability in coaching and support staff, and player health are critical factors in football club performance. The tribal nature of football fandom and club identity can further reinforce these dynamics, creating a complex ecosystem where numerous variables interact to determine a team's success.The Impact of Team Dynamics on Football Club Performance

Conclusion
Form is temporary but class is permanent more telling. Class is long
form and form is short class.
