Riot police have been keeping a watchful eye on West Ham supporters in Prague with over 25,000 having made the trip to the Czech capital for tonight's Europa Conference League final.
Hammers fans have descended on Prague despite only 5,000 having tickets for the showpiece against Fiorentina.
Supporters have been seen lighting flares in Prague's Old Town Square in the hours leading up to kick-off.
Pictures have shown riot police in the square as Czech authorities seek to avoid any potential flashpoints.
Authorities confirmed last month that police would be drafted in from all over the Czech Republic to boost the numbers to more than 10,000 officers.
