In this day and age, pitch invasions can put the footballers on the pitch in serious harm. Who's to say that someone with a knife does not use the invasion as cover to do harm to one or more of the footballers on the pitch.
You can certainly see where the EFL are coming from and Martin Starnes is rightly coming out on the side of the footballer staff, and pitch invasions must somehow be prevented.
The fanbase rightly want to celebrate another end of the season, and some Clubs will be celebrating something more.
From a Health and Safety point of view, Pitch Invasions should not be allowed, but they seem to be a problem that cannot at present be readily resolved easily.
