Referees will clamp down on time-wasting and dissent in the upcoming season - and Julian Alvarez, Thomas Partey, and Mikel Arteta are the first to be punished by these stricter measures.
The Manchester City striker and Arsenal midfielder were booked for kicking the ball away while Arteta was shown a yellow for dissent, all in the first half of the Community Shield clash.
Arsenal's manager had demanded a booking for Rodri after his tackle on Kai Havertz but found himself reprimanded by referee Stuart Attwell.
Harsh crackdowns on time-wasting and abuse are central to new refereeing guidelines, with stoppage time added set to run into double digits.
