Thousands of fans are arriving in Seville

Spanish authorities have been preparing for the mass influx of supporters for Wednesday's match against Porto.

Tickets for the game have been changing hands for hundreds of pounds - although officials have warned fans that they could be buying fakes.

One Celtic fan was taken to hospital after an incident in the city centre, near an Irish bar popular with the visiting support.

Police said a 38-year-old man from Edinburgh had been arrested and that the supporter was undergoing treatment for what are believed to be stab wounds.

Earlier on Tuesday a 17-year-old Porto fan drowned in a river near the stadium which will host the final.

It has been estimated that as many as 55,000 Celtic supporters may travel to Spain for the match.

The authorities have made a plea for fans not to turn up if they have no accommodation but already fans are arriving with nowhere to stay.

The British Consul in Andalucia, Bruce McIntyre, told the BBC's Good Morning Scotland programme that he was confident the authorities will cope.

"I attended a meeting last night and the whole system of securing and policing the event seemed pretty well sown up, so I'm hopeful that everything will go off without any problems," said Mr McIntyre.

"The fans have to do what they can and they will probably spend most of the night in the bars or in the park.

Forged tickets

"I hope they will be moderate in their partying, Seville is a fairly welcoming place but they won't take too kindly to anyone causing fights or that sort of thing."

Uefa and the Spanish police have also issued a warning to fans not to attempt to buy a ticket at this late stage, as it is likely to be a forgery.

"You'll lose your money and you will not be allowed into the stadium," said the Consul.

"Don't waste your money buying your tickets from touts."

Meanwhile, the local press has already been carrying pictures of Celtic fans gearing up for Wednesday, some displaying what they have under their kilts.

Mr McIntyre said that as long as they are isolated incidents the police will just laugh them off.

"Everybody asks the Scotsman what he has under his kilt and he's obviously going to show it, but if there is too much of it perhaps the police will clamp down on it."

In Glasgow, extra police officers are being drafted in to cope with the thousands of fans expected to crowd into pubs and clubs on Wednesday night.

Many premises are screening the game live and police have urged fans to enjoy the atmosphere, but a spokesman said that plans were in place to deal with any problems.
