Nottingham Forest and Leicester City fans have been urged to 'enjoy the game safely' ahead of the FA Cup clash between the two sides.
Steve Cooper's Reds side take on the Foxes in the fourth round of the competition at the City Ground on Sunday (February 6).
The fixture comes a fortnight after the Reds beat arch rivals Derby County 2-1 in a feisty Championship encounter, and another sell-out crowd is expected at the City Ground for the FA Cup tie against Brendan Rodgers' Leicester.
More than 4,000 Foxes fans are expected to make the short trip across the East Midlands for the 4pm kick-off.
Nottinghamshire Police have urged supporters to enjoy the occasion and not "spoil the day for others".
Chief Inspector Neil Williams, match commander of Nottinghamshire Police, said: “Due to Leicester City’s recent success, today’s match represents the first time these rivals have met in nearly eight years, so I understand that both sets of supporters will want to win.
“While we want everyone who is attending the game to have a great time, it is important that people don’t allow their emotions to get the better of them and spoil the day for others."
A Lewis Grabban second half winner secured a memorable 1-0 win over Arsenal last month which saw Forest progress to the fourth round of the cup competition.
Ch Insp Williams added: "As it’s an FA Cup tie, we’re expecting to see twice as many away fans attend today as came to the league match against Derby a fortnight or so ago, but we have prepared for this event and our officers will be on hand to keep everyone safe and ensure the rivalry remains good natured.
“The entire Lower Bridgford stand will be allocated to the away fans for the fixture, so I’d ask any Leicester fan who doesn’t have a ticket but is thinking of travelling to the match anyway not to do so and to stay at home and watch the match on television instead.
“As ever, our officers will be on hand to support fans and both clubs to provide an enjoyable day for everyone in attendance, and we will of course take positive action to keep people safe, should any crime or disorder take place.”
Road closures will be in place close to the City Ground on Lady Bay Bridge before the match kicks off and again after the final whistle. Police have urged drivers to avoid the area during these times.
Seven people were arrested during the game against Derby last month as police investigated reports of a flare being thrown into the away section of the crowd.
Reds chairman Nicholas Randall QC has also reminded supporters to behave responsibly ahead of the Leicester match.
Nottinghamshire Police have also warned supporters not to try and smuggle flares and smoke bombs into the ground, after pyrotechnics were seized by officers during the clash with Derby.
Ch Insp Williams added: “It’s important that anyone thinking of smuggling pyrotechnics into a football ground knows that even going into a stadium with a flare is an offence and could lead to them being turned away at the turnstiles, receiving a football banning order of up to five years, or being arrested.
“Throwing pyrotechnics is extremely dangerous and can result in serious injury, both to yourself and to those around you – it just isn’t worth it.
“Having spoken to fan groups beforehand, we know that the vast majority of supporters will be attending the match just to cheer their side on and to enjoy the feel of another local derby, so our main focus will be to ensure everyone is able to do this safely.”
