FA Cup: Mansfield and Liverpool fans warned over pitch invasions
Football fans attending the Mansfield Town and Liverpool FA Cup tie have been warned that they could be arrested if they invade the pitch.
About 8,000 people are expected to watch the third round match at Mansfield Town's Field Mill ground at 16:00 GMT on Sunday.
Police said fans could also face a ban if they enter the pitch.
It is a criminal offence under the Football Spectators Act 1989 to enter the area of play.
Supt Mark Holland said: "Pitch invasions will not be tolerated. We will be watching today and reviewing footage after the game.
"If you are seen to enter the pitch we will seek to arrest you and, or, make sure you receive a banning order.
"Our aim is simply to ensure order is maintained throughout."
Mansfield Town are in the Blue Square Bet Conference, four divisions lower than Premier League Liverpool.
People not attending the match have been advised to avoid the area around the ground from 14:00 until 19:00 GMT, due to potential congestion.
