Apply the rules equally and fairly for both sides with no taking into account the skill levels of the opposition, what would make the game better in the view of the pundits/neutrals at home should be irrelevant to a referees decision making, make sure a foul in the first minute is penalised the same way it would be in the 81st minute, enforce the various rules in place to stop timewasting, actually give yellow cards to the divers, etc, etc.
The rules are fine, they just need to be applied fairly.
