"Our kicking game and ball retention wasn't great at times, but we are in the semi-finals of the Heineken Cup.
"I am really pleased for the players - they have worked their socks off.
"Against the biggest team in Europe we stood up and were counted, but we are not the finished article.
"We put ourselves under pressure at times, but if we had 36,000 watching us, then it will be nice to push it even higher for the semi-final."
Blues skipper Paul Tito said: "We are pretty chuffed with ourselves, but we are not going to get carried away.
"As captain, I couldn't have asked for any more from the players - the performance showed the character of this team."
Man-of-the-match Gethin Jenkins said: "It's good to get to a semi-final and it's one better than we went last year. It was a boiling hot day and really tough on the lungs.
"I thought the front-five really worked our socks off all game.
"Gareth Williams and Paul Tito really worked hard chasing back for a few kicks. They're a great side, Toulouse, and we did really well to grind out a result.
"It just seemed as if there was wave after wave of attack."
Toulouse lock and former France international captain Fabien Pelous said: "I am disappointed above all, because we had the chances to win this game four or five times.
"There were too many errors in the first half, especially in the first 10 or 15 minutes when we were dominating in terms of territory.
"The Cardiff defence made it very hard for us to break the gain-line. It was very difficult to play our rugby today."
