Leeds manager Neil Warnock defended his decision-making after the 2-0 defeat to Barnsley in the Yorkshire derby at Oakwell.
The visitors struggled to make an impact in attack and were punished after the hour mark when Chris Dagnall struck twice in quick succession - the first coming from the penalty spot.
Warnock said after being booed by the travelling support: "We were very poor in the first half and if I had have been one of the 5,000 I might have said what they were.
"I thought we had some great chances at the start of the second half and then there was a horrendous tackle from (Stephen) Dawson. How that's not a red card I don't know.
"You can't blame the fans... they pay their money. But I think I'm doing a great job if I'm honest and with one or two additions that I've got lined up... I understand their disappointment but we know we need to strengthen."
On the future of leading scorer Luciano Becchio, who is the subject of transfer speculation, Warnock added: "His head wasn't right and that's why the transfer window is such a nightmare for managers. I'll be having a word with him."
