About 200,000 fans are expected in the Welsh capital ahead of tonight’s 7.45pm kick-off at the 74,500-seat Principality Stadium.
Local hero Gareth Bale has, of course, been front and centre for local fans and has been delighted with the response to his arrival with Real, though his level of involvement tonight is yet to be confirmed.
“Thank you for the incredible welcome, fans are amazing,” he said on Twitter.
South Wales Police have urged fans to remain vigilant while reassuring those in the city of the extensive measures to ensure their safety.
An upbeat atmosphere throughout the streets of the city’s streets, fan zones and pubs and bars as fans from Italy, Spain and around the world arrive.
Richard Lewis, speaking on South Wales Polices’ YouTube channel, stressed today was a “great opportunity [for people] to see the city and enjoy themselves.
“Today the focus is on safety and security and ensuring the events run well,” he said.
“Be careful, look after yourself, be vigilant and listen to the advice of the security guards and police officers.
“It’s a really great day, we will be doing all we can to keep everyone safe and secure.
“There will be police about, both overtly and covertly. There will be armed police officers in the Cardiff City Centre, so don’t be frightened, they are there to look after you.”
Fans have also been warned not to attempt to take bags into the stadium and to be careful if attempting to buy tickets, saying that only reputable outlets should be established.
There were huge queues at London stations as ticket holders made their way to trains.
People have reported waiting an hour for their trains as Juve and Real fans nervously check their watches in the hope they will be making the match.
Despite this, there doesn’t seem to be any trouble among fans, reports Walesonline.
Little Jason took to Twitter to applaud the fans.
He said: “Probably a couple of thousand Real Madrid and Juventus fans milling around Paddington station at the moment, zero trouble.”
Extra trains will carry 60,000 passengers, while there will be more than 1,250 coaches, 400 extra flights and 4,0000 new park-and-ride spaces.
