It takes a long time for VAR to be applied. Most of this stems from technological fears that could lose the natural emotions that football brings.

But supporters also have their reasons. According to the Chief Executive of the British Professional Arbitration Association (PGMOL), Mike Riley, VAR will only be used when a turning point of the match occurs, without the referee having a favorable view. .
