The FA, Premier League and EFL strongly condemn the reprehensible actions of supporters who entered the field of play last weekend.
English football has worked hard over many years to ensure that our grounds are safe places.
Everyone involved in staging a game deserves to enjoy the highest safety standards and we are determined to prevent these standards from being undermined.
It is essential that all players feel safe and supported every time they go on the pitch and there is absolutely no place for any type of behaviour that puts this at risk.
We also acknowledge that the overwhelming majority of fans attend football matches to support their team in a positive manner and we will continue to work with those fans, clubs and stakeholders to generate the best possible atmosphere at games.
"It is essential all players feel safe and supported every time they go on the pitch"
Anyone who attends a match to threaten this principle, either from the stands or by entering the field of play, will face the strongest possible sanctions.
The FA, Premier League and EFL wholeheartedly promote the Football Supporters' Federation's "passion not poison" call to respect opposition clubs and fans.
We encourage all supporters to carefully consider their behaviour, not only at this weekend's Premier League, EFL and FA Cup matches, but at all games in the future.
If anyone witnesses unacceptable behaviour at a match or around a stadium please report it to the police, a steward, or use the Kick It Out reporting app (download the iOS app or Android app) or you can use Kick It Out's website reporting form.
