Everton have stated all matchday and non-matchday security arrangements are being reviewed following the weekend's events.
The latest statement comes after Merseyside Police confirmed they were liaising with the club following alleged 'threats' towards Everton directors before Saturday's game against Southampton.
The club released a statement before that clash - which saw protests against the Everton hierarchy - suggesting board members had been instructed not to attend due to a "real and credible threat to their safety and security".
