Barnsley manager Keith Hill believes individual errors are the reason his side are languishing at the wrong end of the npower Championship.
The Reds slipped to a fifth defeat in six games as Cardiff triumphed 2-1 at Oakwell in a victory which sent them to the top of the pile.
After Ben Nugent and Aron Gunnarsson put Malky Mackay’s men two goals up, Jacob Mellis’ effort got the hosts back in it, but they did not have enough quality to earn a point.
Both of Cardiff’s goals came from corners where the scorers were unmarked and Hill insists that is the difference between his side and those at the top end.
“Everything is marginal, they are top of the league and we are near the bottom,” he said.
“We have let (goalkeeper) Luke Steele down. He has made two matchwinning saves and we conceded from both corners and the players are responsible for the individual mistakes they have made.
“The individual errors cost you and that is the difference between the cream and the elite and us at this moment in time. Performance-wise there wasn’t an awful lot of difference between the two sides. But that is the mentality of winning.
“It is the first time we have conceded from set-plays in a while and we have conceded two. That’s what has cost us. We huffed and puffed, we could have had one or two decisions go our way, but we didn’t get them. But we need to show more ruthlessness to make sure the opposition don’t score.”
