Liverpool's Arbeloa blasts Man Utd, Chelsea refs pressure
Arbeloa said: "Ferguson has a lot of experience. He's been doing the same thing for many years. When Ferguson speaks people tend to listen. So many times of course this affects the referee.
"But we at Liverpool are not doing that and still seem to lose out.
"Whereas, every time there is a foul, they go two or three of them together to complain to the referee.
"We don't do that and, at times, this ends up being very important in the result."
Reflecting on their defeat at Manchester United - and Javier Mascherano's dismissal - Arbeloa insisted: "The truth is, you're left with a very bad taste in the mouth when you play such a big derby and the ref is like that.
"In England, they never give you a yellow card in the first five minutes for what Mascherano did.
"United's players were making similar challenges and the ref didn't react in the same way. He left them unpunished.
"The ref made a mistake but now we can't do anything."
Arbeloa added: "I can't believe that they could ban Mascherano for three games. Are you kidding?"
