VIDEO: The Tartan Army descend on London ahead of tonight's England v Scotland match

THOUSANDS of Scottish football fans have made the journey south for tonight’s match at Wembley.

The World Cup 2018 qualifying clash against the Auld Enemy kicks off at 7.45pm tonight, but the Tartan Army have been partying all day in London.

About 14,000 supporters were expected to flock to London for the sell-out game at 90,000-capacity Wembley.

Hundreds of additional seats were added on trains between Glasgow and London, with services from Edinburgh and Glasgow at their busiest this morning.

Return services on Saturday from Euston and King’s Cross stations will also be packed with fans.

Superintendent Alex Carson, who is co-ordinating the British Transport Police operation, said: “We want fans to enjoy themselves and for everyone to have a safe and peaceful journey, but we will have a highly visible policing presence to ensure any anti-social behaviour or crime is swiftly nipped in the bud.”

Videos circulating on social media have shown what the Tartan Army have been getting up to in the capital.

Others attempted the ‘Mannequin Challenge’ on the train down.

The main epicentre for the fans is Trafalgar Square, where earlier a two minute silence was marked as part of Armistice Day.

The match tonight will have a huge impact on Scotland’s chances of qualifying for the World Cup in Russia.

Captain Darren Fletcher says he is looking forward to the ‘monumental’ honour of leading the national side out at Wembley.

He said: “It will mean a lot. Every time you represent your country and lead your country out it is massive. There is no bigger place to do it as a Scotsman, to walk out at Wembley in front of 90,000 fans and 10 team-mates behind you, desperate to get a result and create a bit of history.

“It is a monumental moment and one I am looking forward to and excited about and relishing it.

“We are not going in here with fear or on a real low.

“We get disappointed after results, but it gives you a bit of steel and determination to go out there and try to put it right.

“It is an occasion I am going to try to enjoy. I am sure there will be many more than 14,000 fellow Scotsmen cheering us on and it will be a great occasion and hopefully we can get the result we can remember it by.”
