Liverpool manager Kenny Dalglish has questioned the integrity of match officials following a series of perceived injustices against his team and could face an FA charge after suggesting "people might think there is a conspiracy".
Dalglish's comments follow a weekend of controversial decisions in the Premier League, when QPR manager Mark Hughes suggested managers had "lost faith" in officials and Wigan boss Roberto Martinez railed at "disgusting" decisions that allowed Chelsea to score two offside goals against his team.
Liverpool have just one win in their last nine league games but the manager believes that would be different if a number of key decisions had gone in their favour.
Dalglish feels his side should have had a penalty for a foul on Dirk Kuyt in Saturday's 1-1 draw with Aston Villa, that a Luis Suarez goal was incorrectly disallowed for handball in a defeat to Wigan and thet the Reds were denied a penalty in a 2-0 defeat at Newcastle after the ball hit Danny Simpson's upper arm on the line.
"The last three games there are blatant decisions that have gone against us that are, frankly, inexcusable, and I'd say unexplainable as well," said Dalglish.
"I won't raise it with the Referees' Association, I've raised it now, and it's up to them. I think it really should be their concern. I've raised it, and it's up to them now to look at it.
"If they have something like that [the denied Kuyt penalty], a decision that isn't given that is so blatantly wrong - as we have felt in our last three games - then surely it is their problem, not mine."
Speaking ahead of Tuesday night's Premier League match with Blackburn, Dalglish continued: "I know we have integrity, I know we have integrity in bucketloads, but I can't speak for other people and whether they have integrity.
"What we have to do now, is ensure this football club maintains its integrity, that the players keep their integrity, and hope that people elsewhere have some integrity too. They [referees] have to look at themselves and ensure they are seen to have integrity."
Dalglish went on to suggest that for match officials should explain important decisions to managers after matches, and he is not the only Premier League manager to do so.
"The unfortunate thing for this football club in the last three games is that when there are decisions that are wrong - and there will always be decisions that are wrong - then there is never an explanation of why," he said.
"It would be helpful and more transparent if they told us, if they explained the decisions to us, or even just held their hands up and say, 'sorry I got that wrong', and we can see they have integrity. But they never say anything.
"We don't get everything right, do we? So it is understandable they don't either. But a wee bit of respect towards us would help the situation immensely. Otherwise, people might think there is a conspiracy.
"We can't believe that, we can't let it affect us, and take it into the games coming up, because that would damage us. We have to keep going, and ensure it doesn't affect the players.
"If there is something, then somebody needs to tell us, and if there isn't anything, they need to explain it to us a bit better. We just need to keep going, we can't let it get to that, where we think it's a [conspiracy]."
Liverpool, who have an FA Cup semi-final against Everton this weekend, are 16 points off the Champions League qualifying places.
