Russia's ministry of communications said there had been 6,300 new applications for fan IDs, the document that allows visa-free entry to Russian Federation during the World Cup, since England beat Sweden in the quarter-final on Saturday. Croatia, ranked 20th, is now listed with 4-1 odds to hoist the gold trophy, and they have never made it this far in the tournament.
And, specifically for the crowds back in England, it was a chance to fling all those pints of beer high overhead.
Two teams remain in one of the biggest tournaments in the world.
Croatia have never been to a World Cup final, though they reached the semi-finals in 1998 with a team featuring the likes of Slavan Bilic and Davor Suker.
The tongue-in-cheek video, which they uploaded on their social media page, reminded fans to be "careful when using torches and pyrotechnics", so they can enjoy the game just as much as everyone else.
A first World Cup final since 1966 and a showdown with France agonisingly slipped away.
England should have been two or three goals to the good as they dominated the game for an hour.
"We were anxious", Katich said. If I'm honest, I don't think there are many England players who would get into this Croatian team.
Paul Sealey, who is visiting the area, said: "The team will do all in their power to win".
France has been one of the most complete sides in the tournament, topping Belgium in the semifinal round. Katie - also referred to as Kate - has been supporting the footballer from back home in the United Kingdom since she is due to give birth to the couple's second child any day. "I'll go even if England don't make it, the atmosphere will be great". Croatia was 6/4. Odds Shark had France as -210 to win the final and Croatia +185.
