Not that some of these are not already rules but just need to be enforced.
1 use of arms hands for shirt pulling etc. inside the penalty box- Penalty
2 Video referees- constantly in touch with pitch side ref using replay technology for offside, diving, goals etc. should be no need to stop the game for analysis
3 players not allowed to talk to ref only the team captain or one other nominated person if captain is a goal keeper
4 accurate time keeping by fourth official, for added time at injuries, goals and substitutions. I.e. when play is stopped to when it starts again, none of this judgement of time for subs, goals or injuries.
The current rules allow the ref to be easily influenced by crowd, manager and players.
Don’t mind if the decisions are fair but we all know they are biased and blatantly wrong even when in favour of your own team, it just makes the whole thing a farce at times.
