Liverpool captain Steven Gerrard has blasted referee Howard Webb's "crazy" decision not to award them a penalty in Wednesday night's 1-0 defeat at Arsenal.
Gunners midfielder Cesc Fabregas admitted after the match he had handled Gerrard's stoppage-time free-kick but Webb did not spot it.
Although television replays suggested the incident was outside the area, Gerrard was left fuming at missing out on a chance to salvage a point and maintain their unbeaten run.
As a result Liverpool's winless streak on Arsenal territory still stands at a decade.
"The referee told the Liverpool wall in the first half that if anyone raises their arms above their waist he was going to give a penalty," said the England midfielder. "So for some crazy reason he didn't give it. He told me after the game he hadn't seen it.
"It was unbelievable and I can't believe he didn't see someone raise their hands in the wall. We know over the course of a season sometimes you will get decisions and sometimes you won't, but something so clear as that was hard to take, especially with the referee being Howard Webb."
