Leeds boss Jesse Marsch: "The whole first half we were not in sync and not aggressive enough. We didn't have a full understanding of what this tournament and this game was going to require.
"We need better tactical understanding and savviness and awareness for exactly what matches require.
"We know there's an opportunity back at Elland Road with the draw, and everything is laid out in front of us.
"If we learned one thing is that if you don't show up and you're not ready to play from the beginning, you're going to cause yourself problems."
Cardiff boss Mark Hudson: "First and foremost, the overriding feeling is I'm proud of the performance we put in against a top Leeds side.
"Tactically, we got it right. We showed a good shape. We countered when we could, we frustrated them. We scored two really good goals.
"We knew we would suffer in the second half. They have got an abundance of talent to come off the bench.
"It's not bad when you can bring Rodrigo off the bench."
