Game Conclusion of Independent Report:

The presence of 2 IRD (Incorrect Referee Decision) High (with direct influence on the score and/or number of players) with benefits for Flamengo in the match between Botafogo and Flamengo on 2023/09/02, part of the Brazil Serie A 2023, has completely changed the official score and points for each team. 

The presence of these 2 IRD High with benefits for Flamengo, the distribution of total IRDs (High and Low) with 64% benefits for Flamengo despite the presence of VAR (Video Assistant Referee) , is a potentially abnormal distribution in a professional football match and would require further investigations into refereeing related to manipulation. 

GOAL #2, Referee Error in Failure to Call Midfield Foul which initiates Goal-scoring Sequence


Result of Error: Loss of Possession results in 2nd Goal against, Botafogo loses 1-2

The Foul: Flamengo RB Wesley commits obvious foul to reclaim possession. Play should stop, with free kick awarded to Botafogo, in the Flamengo defensive half of the field - plus a yellow card issued in recognition of the intentional foul which was intended to stop a fast-breaking attack.  


The Goal:  The result of the referee error was an advantage to Flamengo, against a Botafogo defense that was trying to quickly organize, to respond to the unexpected turnover of possession. As the independent report confirms, the goal was the result of a continuous action and should have been cancelled:

Conclusion of Independent Review:

The Goal should have been Cancelled

T0: No Contact by Flamengo player with the ball (green line)

T0+160ms: Foul committed (not whistled) on the Botafogo player (pushing force generated by an extension of the elbow - red arrow)

T0+34 sec: Goal scored by Flamengo 34 seconds after the foul committed, in the case of a fully continuous action (no ball touched by a Botafogo player). The goal should have been cancelled (p.139 Laws of the Game 2023/24 - VAR protocol)

Method of Evaluation: The REF-EVAL® method is the exclusive property of the GOOD GAME!® company. The REF-EVAL® method uses multifactorial analysis of player physiological, biomechanical and tactical performance combined with all refereeing decisions. 

The REF-EVAL® method, developed over 15 years of analysing players and referees performance data, provides more than 99% correct answers on all refereeing situations. The REF-EVAL® method leverages complex algorithms from artificial intelligence (AI) to identify all what are called IRD (Incorrect Referee Decision) to be opposed to CRD (Correct Referee Decision). 

We then distinguish between IRD High, i.e. referee errors that directly influence the score (e.g. an invalid penalty whistled...) or the number of players (e.g. a red card not given…) and IRD Low, i.e. referee errors that do not directly influence the score (e.g. a foul not whistled...). In the same way we distinguish the CRD Low when the referee makes the right decision on a simple decision, from the CRD High when the referee makes a right decision on a complex situation (a penalty rightly whistled for example).
