Leeds boss Daniel Farke felt his side should have been awarded two penalties in their goalless home draw against Sunderland.
United missed the chance to go top of the Sky Bet Championship after being denied a 10th straight home league win after leaders Leicester had slipped to a 1-0 defeat at Millwall.
A first-half cross struck Sunderland defender Dan Ballard on the elbow and a second-half corner hit visiting skipper Luke O’Nien on a raised hand, with both penalty shouts for Leeds turned down by referee Tim Robinson.
Farke said: “We didn’t create enough clear-cut chances. That’s why we didn’t win this game.
“I also have to say, we were pretty unfortunate with several decisions today. It was a clear handball in the first half, should have been a penalty, and a clear handball in the second half, should have been a penalty.
“If there is a rule how there should be a handball, I ask just for the rule.
“I think we’ve had six letters during the season so far apologising for (not being given) a penalty or for red cards – we’ll probably get two more letters now, but it won’t help us.
“They were decisive moments, but credit to Sunderland I think. In the last five games they’ve had four clean sheets.
“I’m annoyed with the (penalty) decisions because they were decisive, but I also like to be self-critical and today we didn’t create enough clear-cut chances.”
Sunderland had won only one of their previous eight league games under interim boss Mike Dodds, but have had clean sheets in four of their last five and proved a tough nut for Leeds to crack.
But Dodds, placed in temporary charge for a second time this season when the Black Cats sacked Michael Beale in February, was in no mood to celebrate his side’s hard-earned point.
Dodds said: “I’m happy for them, but I don’t want to go over the top. I’ve just said to them that we have drawn the game, we haven’t won it.
“There were a lot of positives, but we have drawn the game and I don’t want to be sat here celebrating draws.
“Our out-of-possession stuff was excellent. I didn’t feel at any point that Leeds were going to score or break us down or carve us open.”
Dodds would not be drawn on whether Leeds should have been awarded at least one penalty.
“The reality is that these decisions are swings and roundabouts. It would have been unbelievably cruel on us,” he added.
“I felt all their chances came from our sloppy play and I just said to the group my biggest disappointment was our quality with the ball.
“Our evening would have been a lot more comfortable had we not turned it over far too much.”
