Celtic fans have been urged not to attend an unofficial "title party" in Glasgow after the last game of the Scottish Premiership season on Saturday.
Thousands of supporters are expected to descend on the Merchant City and Trongate areas after the club lift the league trophy following the game against St Mirren at Celtic Park.
The mass gatherings, which are not supported by the club, Police Scotland or Glasgow City Council, have attracted anti-social behaviour, damage and disruption to the local area in recent years.
However, the local authority said there had been no proposals for a formal "fanzone" event to be held anywhere in the city.
About 25,000 people attended the gathering last year, resulting in 19 arrests, injuries to four police officers and a massive clean-up operation the following day.
Glasgow City Council said a "substantial" amount of litter, debris and broken glass which was left in the area was cleared.
