Regarding the video assistant referee (VAR) system in football, how about adding a few rules about its use? For example, the on-field referee could only request VAR if they were really uncertain about a situation, not just to “make sure”, and off-pitch officials could only give their opinion if the referee asked them for it (23 November, p 40).
And a system similar to the one for disputed line calls in tennis could be implemented: the team captains or the coaches could challenge a decision, which would then be checked by VAR, but each team would only have a set number of challenges.
