Goals from Kenny Miller and Anthony Gerrard condemned the visitors to a 2-0 defeat at Cardiff City Stadium as the Bluebirds did their bit to lift the spirits of a nation rocked by the death of Wales manager Gary Speed by reaching the last four of the Carling Cup for the first time since 1966.
Prior to the game a tribute was paid to Speed when the stadium united in a round of applause in recognition of his career before a minute's silence.
Both managers and Football Association of Wales chief executive Jonathan Ford also laid floral tributes on a Welsh flag, and during the game there were chants of "there's only one Gary Speed".
And Cardiff manager Malky Mackay said the result was a fitting tribute.
"I am very proud of the group, and proud of everyone at the football club," he said. "It was an emotional evening for everyone at the club and everyone in Wales.
"We knew that going out tonight we would have a big attendance and it was a very moving tribute to Gary.
"We wanted to get through just as that little tribute to him to get Wales into the semi-finals of the Carling Cup."
