Boss Alan Pardew was unhappy after Blackpool claimed a 1-1 draw against his Newcastle side with a contentious equaliser.
DJ Campbell was awarded a goal when his near-post flick was adjudged to have crossed the line in the 32nd minute of a frantic Barclays Premier League clash at Bloomfield Road.
That goal, given before Luis Enrique headed clear, cancelled out a 17th-minute strike from Peter Lovenkrands.
"The goal was disappointing because I think you have got to be beyond doubt if you are going to give that," he said. "Seeing it again it certainly doesn't look like that.
"If you are 40 yards away you have got to be beyond doubt it is over the line and it doesn't look like that to me.
"Having said that, they deserved a goal for their play and their intensity. They gave us a lot of problems."
