Assistant manager Scott Young admitted Cardiff's 0-0 draw at home to Millwall on Saturday had been hard going.
Cardiff remain becalmed in mid-table after the result, which saw Millwall gain a precious point in their Championship relegation fight.
"It was not a great game or a great spectacle," Young said.
"Millwall came with a plan to slow the game down and make it a niggly affair, they spoiled the fluency of the game and we could not get any momentum."
Midfielder Joe Ralls came closest to scoring for the Bluebirds, hitting the Millwall bar with a cross-shot.
But Lions defender Mark Beevers later struck the bar after beating Cardiff goalkeeper David Marshall, while Gary Taylor-Fletcher trod on Ricardo Fuller's pull-back with the goal at his mercy during the dying moments.
"They have got the point so credit to them," Young added.
"We try and give the fans something to smile about every time we go onto the pitch and we are as disappointed as the fans.
"We edged the first half but give them credit, they were probably the better team in the second half.
"But I wouldn't say they deserved to win the game. We had some good moments ourselves. We had some chances but we could not make the most of them."
