Liverpool boss Kenny Dalglish has taken aim at Manchester United rival Sir Alex Ferguson over his rant at ref Martin Atkinson.
Dalglish has told Ferguson to show some respect.
While the Liverpool boss avoided naming Ferguson directly, there was little doubt who he was referring to when he said: "Sometimes I worry that the ones who shout the loudest get more beneficial decisions - and that is totally unfair.
"This week the theme has been about referees and I've got to say that when I came back in as manager I was made fully aware of the respect campaign with regard to officials. I think we have adhered to the campaign in every respect.
"We have never come out and criticised match officials in an of our games.
"They have made mistakes in all of our games, but we've also made mistakes.
"It is impossible for officials not to make mistakes. But there is a respect campaign in football and I want to know whether we are going to be the only ones that adhere to it."
