Guy Luzon believes his side’s limp 2-1 defeat at the hands of Cardiff City was down to nothing more than a lack of commitment from his players.

Having gone ahead through Karlan Ahearne-Grant early in the second-half, the lead was lost within four minutes with a Joe Mason tap-in, before Sean Morrison headed the winner 14 minutes from time.

With the visitors struggling to deal with the Bluebirds’ set-pieces, Luzon told Sky Sports his defenders had to man-up and keep more clean sheets.

“It’s very difficult and we are very disappointed,” he said. “We were leading 1-0 and we need to show character to keep the result and to keep the clean sheet.

“It was very disappointing to concede so soon after we scored and, from set-pieces, we need to show commitment. You need to be first to the ball, but they were first to the ball and in the end, we paid for it.”

“Of course, I expect them to win the dual and to take the first ball. They won every duel from set-pieces and we paid for it.”

He took the chance to praise Aherne-Grant for his contribution from the subs bench, but it wasn’t his attackers he was gunning for.

“I took our winger off and added another striker. He did well and he scored, but in the end we did not lose because of the offensive side, we lost it because of the defensive side and our commitment.

“We can fix that in training and give them the message. But in the end, every game we lead 1-0, we need to keep a clean sheet. That is the base we need to start from.”
