Of top tier/high prestige competition, including both club and international football, which tournament has the fairest refereeing throughout the years? The UCL? World Cup? Euros? One of the top domestic European leagues? Factors include quality of referees and decisions, good VAR usage, least corruption etc.
Bundesliga is the best.
La Liga is the absolute worst, to the point that most La Liga games are unwatchable because of the Spanish referees.
If they are worse than those from PL, then this is just horrible
