Sunderland fans have been warned they won't be able to take over Trafalgar Square and other parts of central London when over 40,000 descend for Saturday's League One Play-off final.
Previous visits to Wembley by the Mackems in 2014 and 2019 have seen tens of thousands of fans drinking and singing in the streets.
But the Metropolitan Police Football United has warned Sunderland fans - and those following their opponents Wycombe - that street drinking won't be permitted this weekend after Westminster Council took action to prevent it.
They tweeted: 'A warm welcome to travelling Sunderland and Wycombe supporters for this weekend.
'Please be aware that due to the Public Space Protection Order street drinking is prohibited in all of Westminster.
'There are lots of licensed premises to enjoy a drink. Good luck to both teams.'
In addition, street drinking restrictions now exist for Wembley Way and the vicinity of the national stadium after Brent Council changed the rules following the carnage at last year's Euro final between England and Italy.
In 2014, Sunderland fans visiting London for the League Cup final against Manchester City - their first visit to Wembley in 16 years - packed the streets around Covent Garden.
On that occasion, some central London pubs had to close at around 9pm on the Saturday night, the even of the game, because they'd run out of alcohol.
Nearby supermarkets also sold out of beer as 40,000 Sunderland supporters drank them dry.
The invasion led to condemnation from the Conservative MP Robert Halfon, who tweeted: 'Went to London for dinner. Wish I hadn't. Scumbag football hooligans turn Covent Garden into a disgusting cesspit.'
In 2019, Sunderland fans twice took over Trafalgar Square when they visited for the EFL Trophy final against Portsmouth in March and then the League One Play-off final against Charlton Athletic in May.
Fans draped Sunderland flags on the square's famous fountains, chanted, lit red flares and drank booze.
On that occasion, the Met's Football Unit was more accommodating, even tweeting out pictures of the sea of red and white.
This time, however, the authorities have taken steps to avoid a repeat of the scenes after Sunderland sold over 44,000 tickets for Saturday's final. Wycombe have shifted just under 20,000 tickets.
The Black Cats have been stuck in League One for four seasons now and will be desperate to get back to the Championship after a string of agonising near-misses.
They finished fifth in the table during the regular season and then defeated Sheffield Wednesday 2-1 on aggregate in the Play-off semi-finals.
