Leeds United supporters are being advised to stay at home for the club’s final match of the season on Wednesday.
Fans gathered outside the club’s ground during the weekend after the club won the Championship and was promoted to the Premier League.
On Sunday, 7,000 people crammed into the city’s Millennium Square.
Leeds City Council and police have warned fans not to recreate previous incidents when the club hosts Charlton Athletic on Wednesday at Elland Road.

The gatherings were mostly calm, but a few fans in Millennium Square did throw bottles at police officers.
West Yorkshire Police said a female officer who suffered a head injury has been released from hospital and is recovering at home.
The city council has stated that it will celebrate the club’s achievement with a civic banquet as soon as possible, but a city-wide march is not now possible.
Mohammed Rafique, a council executive member, said he understood fans’ want to rejoice.
“We are however, as a city, continuing to tackle coronavirus, and it is absolutely vital, therefore, that people do not seek to replicate what we saw in Millennium Square or in any other venue in the upcoming days,” he went on to say.
He noted that the coronavirus advice, which prohibits big gatherings, was in place to protect people’s health and well-being.
“We would urge people to remain mindful of the government restrictions and remember that the best way to celebrate is at home,” stated a West Yorkshire Police spokesperson.
“We must not lose sight of the fact that Covid-19 is still with us and that large gatherings are not permitted.”
