Missed the games so far but reading up on BBC I see Palace had a free kick goal disallowed because a player was within 1 metre of the wall (or something like that). It's not a rule I remember seeing before. Is it something commonly applied or a new rule?
As per the BBC:
Simply, the goal was chalked off because a Palace player was standing too close to the Chelsea wall.
Referee Darren England made an announcement to the crowd to explain the decision.
He said: "After review, away number six is less than one metre away from the wall as the shot is taken. Therefore, it's an indirect free-kick and a disallowed goal."
The International Football Association Board's Law 13 states that when three or more defending team players form a wall, all attacking players must remain at least one metre from the wall until the ball is in play.
This rule was introduced to the laws of the game in 2019-20.
