Millions of people around the world are gearing up for kick-off at the FIFA World Cup in Russia - which is just two months away. But there is a minority of people who are getting ready for something much more intense.
When the Euros were held in France in 2016, one of the biggest items of news happened off the pitch and in the streets, when hooligans from England and Russia clashed.
Shit got undeniably hectic when the two teams played each other in Marseille, where ultras flew over just to cause mayhem. The Telegraph reports up to 150 of Russia's 'strongest' hooligans travelled to the French city to send a message to the English fans.
But this year's World Cup will be on Russia's turf and they're warning the Three Lions to expect even more blood, sweat and tears.
The Daily Star reports that posts on a hooligan page on Russian social networking site Vkontakte says they're planning on 'unleashing hell'.
One post reads: "They'd better go to the gym and prepare themselves somehow," while another states: "You want a war, then you will have it. Fighting is in our blood - this June we will do more than just sing." The various ultra pages show off brawls, concealed weapons, injuries and dogs. There are even videos showing what looks to be training sessions for fights.
National Police Chiefs' Council national football policing head deputy chief constable Mark Roberts has already issued a warning for England fans as they head to Russia in just two months.
He told the Telegraph: "There are risks, because if you look back to what happened in Marseille, there were Russian supporters there, intent on causing significant disorder and causing significant injury.
"You only have to go on YouTube to see that there is an active hooligan issue in Russia and it generally operates at a pretty extreme level of violence. There clearly is a potential issue.
"The balance to that then is, 'Do we think the Russian police are going to treat it seriously? Is there a commitment from Russian state to treat it seriously?' And I think, everything I've seen, the reassurance is there."
He also suggested that English fans have a tendency to provoke an opposition's fan club by singing songs deliberately meant to stoke a feud. Constable Roberts said if the Three Lions hooligans want to do that in Russia, they can expect a pretty tough response from the police.
