The guidance on this isn't to penalise the player who encroached if they get involved in any way though, as far as I recall, only if they get involved in either scoring or preventing a goal.It was an interesting one. There's no doubt he was encroaching, and I thought if he then got involved after the save he would be penalised, but PGMOL seem to say that as he didn't stop a Chelsea player from getting the ball it was OK.
Encroachment can only be reviewed if:
• an attacker who encroached scores or is directly involved in a goal being scored
• a defender who encroached prevents an attacker playing or being able to play the ball in a situation where a goal might be scored.
