Cardiff boss Malky Mackay rued his side's poor finishing in a 2-0 loss to Crystal Palace, but felt the defeat was just "one of those days".
Cameron Jerome and Marouane Chamakh helped Palace to a comfortable 2-0 win, on an afternoon where the visitors struggled to create much going forward.
Mackay admitted his side's profligacy was the main reason for the defeat.
Talking to Sky Sports, Mackay said: "We didn't take our chances and Crystal Palace did, it's as simple as that.
"On another day we score, but Palace took those chances. It's one of those days.
"It's fine lines, and confidence can shape games."
Cardiff came into the game sitting in 15th place, four spots and four points above their hosts.
Defeat at Selhurst Park, however, means that the gap is now just one point, and the Welsh side are embroiled in a relegation battle.
Mackay expected a difficult clash with Palace, though, in light of the London club's new-found confidence and steel under new manager Tony Pulis.
"They certainly were at it, but we knew that," Mackay said.
"They've got a new manager which brings a bit of buoyancy, and it's a tough place to come.
"It's just being clinical. People need to stick the ball in the net. Today there's been a couple of good saves.
"It's a bad result for us today, especially after Stoke midweek."
Mackay did not seem too concerned on his side's performance overall, and saw promise in their battle against relegation.
"Overall, we've been playing well. We just need to keep believing in ourselves."
