Rule changes 2019/20 season

There are going to be several changes to the laws of football next season apart from the one about handball....

The five major rule changes
  • Accidental handball goal won’t stand
  • GK’s allowed one foot off the line for penalties
  • Substituted players can leave the field anywhere
  • No attacking players in the wall
  • Coaches will receive cards

What's the philosophy behind not having attacking players in the wall? Coaches receiving cards is going to be very interesting indeed.
 
2. Goalkeepers allowed one foot off the line - Why? It's a penalty why make it easier for the offending team

4. No attacking players in the wall? I assume they mean no opposition players in the wall it is very ambiguous this one.

1 accidental handball will still cause controversy imo

3. Substituted Players can leave the field anywhere - this should have read 'must leave the field at the nearest point of exit from the pitch and in any case within 20 secs if not injured)

5. coaches can receive cards - what colour - Is the 4th ref in charge of this, why stop a game to facilitate this rule.
