Millwall face Dagenham and Redbridge in the FA Cup on Monday and there are growing concerns that a number of West Ham fans have bought tickets for the away game at the Den.
The Hammers have not faced their old enemies since 2012 and, perhaps surprisingly, there have been no restrictions on who can buy tickets.
Last week, Dagenham and Redbridge, the National League team with close links to West Ham, sold more than 1,300, and the Met Police, who deemed the match low risk, are aware of the situation.
Meanwhile, large numbers of Manchester United fans are believed to have cheered on Salford City Class of 92 at the Etihad Stadium on Saturday.
The visitors usually count on a crowd of 2,800, but large sections of 5,000 supporters sang a variety of United songs.
There were no reports of major problems.

The Olympic world is watching anxiously as Los Angeles, host of the 2028 Games, continues to be devastated by wildfires.
With a firm contract for the host city (as Tokyo discovered during Covid), it will be interesting to see how the seven IOC presidential candidates answer questions on this issue when they meet in Lausanne in two weeks.
There are also concerns that the spread of the fires could threaten sites, including the 100-year-old Riviera Golf Club, which is five miles from the Palisades Fire and within the evacuation zone.
Meanwhile, a Team GB delegation currently in California inspecting its San Francisco-based pre-Games training camp was due to be in some of the Los Angeles districts most affected by the fires later this week.
However, Inside Sport understands that they quickly returned the accommodation they were due to stay in to support the rehousing of affected Los Angeles residents.

Sir Gareth remains (mostly) silent

While some believe the men's game often drags its feet on player welfare issues, the women's game is showing it is prepared to think differently as it embarks on a new professional era.
In the Sports Industry Report 2025, released Tuesday, WSL director Nikki Doucet says she is exploring ideas with women's health organizations to work on studies and educational programs that will improve training, inform the development of products and will prevent injuries.
Doucet believes she can give women in and out of the game access to better guidance on how to lead active lifestyles.
