Cardiff City boss Erol Bulut told BBC Sport Wales:
“Disappointing about the result but not for the performance over 90 minutes and what we showed today.
“I think it was more upsetting to lose three points because at least one point we should have got, because for 90 minutes we controlled the game.
“We made a mistake from a free-kick, our concentration was not like it should be.
“We tried to come back into the game and we had chances to score but we couldn’t manage it. But today we can speak more about positive things than negative things.”
Sunderland boss Regis Le Bris said:
“It wasn't easy to start away, especially here at Cardiff. The game was tough.
“We started well I think, and when we scored the goal, the game changed because Cardiff took more risks.
“Sometimes we had some good sequences but for the whole game, it wasn't dominant. The satisfaction is the team spirit. Even when we were not dominant, we kept the organisation.
“I'm happy because we won and this is our main goal. Sometimes the balance of the game is not the one expected, so we need to deal with it.”
