Arsenal
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.
"I would say he is one of the best referees in the league so I
am very surprised he didn't see it."
