Liverpool manager Kenny Dalglish has claimed that the penalty which cost his side at Stoke City was another bad call against his players this season.
The Reds went down 1-0 at the Britannia Stadium to a Jonathan Walters penalty after Jamie Carragher was adjudged to have fouled the winger.
The Scot also suggested that he is considering action against officials should it continue.
"The first four games have had contentious decisions in them and every one has gone against us," he said.
"If I feel the club is suffering in any shape or form I will need to go the same route other people go and see if we can gain some benefit from that.
"I'll speak to the owners first and see what they say because the last thing I want to do is for my behaviour to impinge on the club's success in any way."
Liverpool currently sit fifth in the Premier League and face a trip to Tottenham Hotspur next Sunday.
