Sheffield United boss Danny Wilson watched his team come from behind to extend their unbeaten run in League One with a 1-1 draw at Scunthorpe.
"We can't be too disappointed to come away from home and get a point," said Wilson. "But the way the game panned out in the second half I did think we could have forced it a bit more.
"We had a lot of pressure but too many times our final ball wasn't good enough. I didn't see the incident which led to their player being sent off but the fourth official said it was for a dangerous challenge.
"I did see the goal that Dagnall scored to put Scunthorpe in front and I'm sure he will think of it as one of his best but from our point of view it was a woeful one to concede. In the second half Scunthorpe battened down the hatches and defended for their lives."
