Blackpool boss Ian Holloway admits he is still 'spitting feathers' following the weekend defeat to Arsenal.
The Tangerines went down 3-1 at home to the Gunners and Holloway has now called for the introduction of video technology to help match officials.
He was unhappy about a number of decisions made by Lee Mason, including a Laurent Koscielny challenge in the box on Gary Taylor-Fletcher.
"Last week, we almost turned it around against the second-best team in the league at the moment," Holloway said.
"Within five minutes, we should have been at 2-2 and I am spitting feathers about that - almost venom - because how many times this season have we had that?
"The viewers at home will have seen it - Manchester City at home, Manchester United when we were 2-0 up, with the penalty we should have had when Luke Varney was barged sideways.
"Can't see it, didn't give it - how many times does that happen?
"I wonder if it was up the other end they might have seen it? It might have been an easier decision for them. It has happened too many times for my liking."
He added: "When Gary Taylor-Fletcher has rolled it off to someone and his legs are scythed from underneath him, surely you can see that and that it is a penalty - in my opinion.
"I've watched it and had a week to reflect on it and I still feel the same. I wonder how many other managers of smaller clubs feel that way as well?
"Once I watched it again, I had to bite my lip. I cannot believe what I saw - at that moment, when we had just got back to 2-1 and we had the impetus.
"It was there and it was taken away from us again."
Meanwhile, Blackpool host fellow strugglers Wigan on Saturday but will be without midfielder David Vaughan, who has injured his hip.
"We are seeing a specialist this afternoon," Holloway remarked.
"There is slight muscle damage, but there is a fear that it might have pulled a piece of bone off his hip.
"I'm trying to concentrate on the ones who are fit, and I know David isn't for this weekend - I'll leave that to my physio."
