Merseyside Police are urging fans attending the Everton v Liverpool derby this Saturday to take a "sensible approach" to alcohol.

They warn a "selective" search operation will be in operation at Goodison Park and supporters are being advised to attend well in advance of the kick-off.

The force had applied to change the 5.30pm start of the match due to concerns it would increase the risk of alcohol-fuelled disorder, and made a legal challenge.

Liverpool City Council had refused to amend Goodison's ground safety certificate to allow an earlier start.

During discussions at South Sefton Magistrates' Court on Monday, Everton agreed to further segregation arrangements.

Lawyers for the police withdrew their case once additional arrangements were agreed.

Superintendent Chris Markey said: "We are looking forward to Saturday's match, it is usually a very lively and memorable occasion which attracts a worldwide TV audience.

"While we have made our position quite clear with regards to the kick off time, there will be no change to our policing style which will be firm, fair and friendly as it always is at football matches on Merseyside.

"As such, officers will be doing all they can to ensure supporters are safe and can enjoy the occasion both at the stadium and elsewhere.

“Fans have been afforded more time before the game to socialise and have a drink.

"This is all part of the match day experience - however I am urging supporters not to drink to excess, which can result in anti-social or even criminal behaviour.

"We have worked closely with the club, supporters groups, the city council and local bars and pubs leading up to the game to minimise any problems and to promote a sensible approach to alcohol intake.

“At the stadium, Everton Football Club has plans in place, supported by ourselves, to ensure the safety of supporters." 

Supt Markey said this includes a "selective" search operation.

"Supporters are advised to attend well in advance of kick off time to facilitate a timely entry into the stadium.

"I would also remind all fans that anyone who is deemed to be drunk will not be permitted to enter the stadium."

"This fixture has a long history and unlike other city-based derby games it is likely that small numbers of Liverpool supporters may have obtained tickets for the home areas.

"Everton have undertaken to fully enforce the ground regulations for this fixture in respect of segregation.

Any away supporter seeking entry to home areas of the stadium will not be permitted entry irrespective of whether they have a ticket for that area of the stadium.

If an away supporter is identified in home areas, they may be ejected.

Supt Markey added: “Unfortunately, we have seen the use of pyrotechnical devices at grounds around the country, while at Goodison Park itself there have been incidents of missile throwing and supporters entering the playing area on occasion.

"Such behaviour, albeit committed by the very small minority, amount to criminal offences and put the safety of other supporters at risk.

"I would remind supporters that the CCTV system inside the stadium is excellent and allows both ourselves and the club to identify offenders at the earliest opportunity."

He said the force will have a substantial policing operation in place for the game, which covers not only the stadium but also the city centre and other areas across the county.
