The match is a very big rivalry, and you can feel the weight of the match in the city, as revealed by West Ham's Morato. The last match between West Ham and Millwall was in 2012, and since then, the two teams have not faced each other in an official match due to being in different divisions of the English football league. This Saturday, the re-match will take place in the second division national league.
The match has a long and complex history, with the two teams having a strong connection to the communities that worked in the docks of the River Thames. The rivalry has also been marked by violence between fans, particularly during the peak of hooliganism in English football. The tension before the match has already appeared on social media, with a Millwall fan posting a video with threats and insults directed at West Ham's Tomas Soucek.
A special operation will be carried out by the Metropolitan Police of London, with around 400 officers being mobilized, a number above the usual used in Championship matches.
