Ahead of the 2019/20 season, we look at the new things to keep an eye out for in the Premier League.
The International Football Association Board (IFAB) has updated the Laws of the Game, and we are examining what has changed.
Managers and coaches will have to be on their best behaviour and set a good example as they can now be shown yellow and red cards for misconduct.
Any team official deemed guilty of an offence can be cautioned or sent off.
And if the offender cannot be identified, the card will be shown to the senior coach in the technical area, usually the manager or head coach, as the person responsible for the other team officials.
An experiment with this approach has been successful and revealed benefits at all levels, including for young referees dealing with difficult adult coaches.
