The varying interpretations of handball across different leagues are a major concern. The Premier League had the most relaxed interpretation of handball last season, with a handball penalty every 17.27 games. In contrast, the Champions League had a penalty every seven games - the highest frequency in Europe. This highlights the difficulty in reaching a consensus across competitions.
Rosetti believes that lengthy VAR reviews are a particular concern, with any check longer than 90 seconds risking "losing credibility". To address this issue, a new collective protocol was agreed, where referees would be shown a freeze-frame for point of contact, followed by half-speed, and then full speed for the intensity of the challenge. The Premier League had the lowest intervention rate in Europe at 0.29 per game, while the Champions League was 0.47 per game.
Rosetti said that there were "too many reviews" and more interventions were affecting player behaviour, with attempts to play for or earn video decisions. He referenced incidents like Diego Maradona's 'Hand of God' goal for Argentina against England at the 1986 World Cup, stating that VAR should only intervene for clear and obvious situations.
Clear Line aims to provide a guide for fans to understand VAR better, with video examples of handball situations to explain what is considered an offence. The portal goes through each area the VAR covers - penalties, red card, attacking offences, factual decisions and mistaken identity - in great detail with video examples.
