Cardiff manager Malky Mackay dedicated his side's Carling Cup win over Blackburn to Gary Speed, as the Bluebirds reached the semi-finals of the competition for the first time since 1966.
A Kenny Miller strike and a goal bundled in by a combination of Anthony Gerrard and Filip Kiss condemned the visitors to a 2-0 defeat at Cardiff City Stadium, as the home side lifted the spirits of a nation rocked by the death of Wales manager Speed at the weekend.
Prior to the game, a tribute was paid to Speed when the stadium, which hosted his last game in charge of Wales, 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 laid floral tributes on a Welsh flag, and during the game there were chants of "There's only one Gary Speed".
Mackay said the result was a fitting tribute.
"I am very proud of everyone at the football club. It was an emotional evening for everyone at the club and everyone in Wales," he said.
Leeds manager Simon Grayson dedicated his side's 4-0 win at Nottingham Forest to Gary Speed, as the club's supporters paid their own affectionate tribute.
Grayson played and earned his coaching badges with Elland Road old boy Speed, and asked his Leeds players to win the game for his friend. Goals from Robert Snodgrass, Jonny Howson, Luciano Becchio and Adam Clayton ensured they did.
