Cardiff City manager Neil Harris told BBC Sport Wales:
"The difference tonight is that they were better than us in both penalty areas. It was sixth v fourth, so I knew it would be a tight game.
"The penalty, was it a penalty, was it not? I think it is soft at the end of the day, but he's a clever striker, the best in the business at this level. I think the referee was naive there.
"We got into some good areas, but didn't win any second balls.... that is the frustration.
"I will never be happy with a defeat, but the performance was strong. The performances have been strong since March. We have got to earn the right to stay in the top six."
