Tens of thousands of Rangers fans are in Seville ahead of one the biggest matches in the club’s history.
Police expected up to 100,000 supporters of the Glasgow team to travel to the Spanish city for the Europa League final.
They will be joined by 50,000 fans of German side Eintracht Frankfurt.
The vast majority of those who have travelled do not have tickets for the game in the 42,700-capacity Estadio Ramon Sanchez Pizjuan.
Only 9,500 tickets were originally sold to Rangers fans, although more are believed to have been made available in recent days.
Ticketless Rangers fans will be able to watch the match at the 57,000-capacity Estadio La Cartuja in the north of the city – where Celtic lost the 2003 Uefa Cup final to Porto.
Former Rangers captain John Greig, who led the team to victory in the European Cup Winners’ Cup Final in Barcelona in 1972, wrote an open letter to fans ahead of the final urging them to be “ambassadors” and show the “absolute best” of the club.
He added: “To see Rangers in a European final is something many of us thought would not be possible again, and I’ve been so taken by the incredible lengths you are going to in order to reach Seville to back the team out there.
“It is vital that we all act responsibly and remember the values that this institution stands for.”
Seville Police said they were prepared for large numbers of supporters in the city for the match – which kicks off at 20:00 – with about 5,000 officers on duty.
Many bars in Seville will be closed on Wednesday, but fans will be able to watch the game on big screens around the city.
Rangers have travelled from across the globe to watch the match, with some travelling from as far as Australia despite not having tickets for the game.
Brian, originally from Nairn, spent 40 hours travelling to Seville from Sydney. He bought a match ticket on Tuesday for 1,600 euros (about £1,350) and reckons he has spent about £5,000 on the trip so far.
“And that doesn’t include any drinks, so you can double that!” he told BBC Scotland. “It is money well spent. I didn’t travel from Australia not to see the game.
“I am 54, I have been a Rangers fan my whole life and will probably never see this again in my lifetime.”
More than 400 flights arrived in the city on Tuesday, with a similar number – including 16 charter flights from Glasgow Airport – expected on Wednesday, with trains and coaches travelling to the city also full.
