In what is certain to be a hugely emotional affair, Wales face one of the most important matches in their history tomorrow at Cardiff City Stadium when they take on embattled Ukraine for Europe's final spot in the 2022 World Cup in Qatar.
There will understandably be a lot of emotional support for war-ravaged Ukraine, but in pure football terms it is also a momentous opportunity for Wales whose last appearance in the World Cup was 64 years ago.
Ukraine have been boosted by their impressive performance against Scotland at Hampden Park on Wednesday night to give themselves a chance of reaching the finals.
It would be an extraordinary story if they were to make it to Qatar in November.
In Glasgow, the Blue and Yellows outplayed the Scots and were deserved 3-1 winners.

"It was disappointing," said Clarke.
"Sometimes the opposition plays better than you and that was the case tonight."
It means Scotland have failed to qualify for the last six World Cups since 1998.
Although the result was a huge blow for Scotland, as a nation they can take pride in the welcome they gave the Ukraine team and it was a rare time the Hampden crowd joined in the singing of their opponents' national anthem.
Ukraine manager Alexsandr Petrakov, who went on a walkabout in Glasgow before the game, thanked the Scottish people for their warm reception.
"I was touched by their support," he said.
Now the Ukraine players have to shake off the euphoria and concentrate on the match against Wales.
It will not be easy because Wales manager Robert Page has created a well-organised side to prepare for what he calls the "biggest match in Welsh history."
The winners will join England, the USA and Iran in the opening group stage.
At the same time, Ukraine were demolishing Scotland, the Welsh lost 2-1 away to Poland in the Nations League.
But with one eye on tomorrow's big game, Wales did not field stars like Gareth Bale, Aaron Ramsey and other first team players and were content with their performance against Poland.
For a small country, Wales have produced a lot of talent highlighted by fine performances from John Charles and Ivor Allchurch in the 1958 World Cup in Sweden.
They were eventually edged 1-0 by mighty Brazil in the quarter-finals, the only goal being scored by a 17-year-old lad called Pele.
Since then Wales have produced many fine players but none has had a chance to perform in the World Cup.
Names that spring to mind are Ian Rush, Ryan Giggs, Mark Hughes, Neville Southall and Bale.
More recently Welsh fans will look back fondly on the 2016 Euro tournament in which the Dragons, led by Bale, made it to the semi-finals before losing to eventual winners Portugal.
Bale, born and bred in Cardiff, appears to enjoy playing for his country more than Real Madrid and tomorrow will once again be the key to Welsh hopes.
The fans will be doing their best to get their team through and you can be sure to hear hearty renditions of Men of Harlech.
Caretaker manager Page has proved an efficient replacement for Ryan Giggs after taking over in November 2020.
Since then he has taken Wales to the last 16 of Euro 2020 and is now on the brink of securing a World Cup place.
Page, who was raised in the Rhondda Valley, is a no-nonsense gaffer and has "zero tolerance" of ill-discipline.
He is also a great admirer of Bale who scored both goals against Austria in March to put the Welsh into the play-off final.
"Gareth deserves all the credit for making it work with us," Page told the Daily Mail recently.
Bale should also be in good spirits having been awarded an MBE by Queen Elizabeth.
Whatever the result at Cardiff, it is going to be a passionate game and let's hope it will be a match that all football supporters will be able to look back on with pride.
