Liverpool captain Steven Gerrard has blasted Howard Webb after the referee failed to award the Reds a "stonewall penalty" as they crashed out of the FA Cup on Sunday.
The Reds were beaten 2-1 by Arsenal and were denied a spot kick when Luis Suarez was bundled over by Alex Oxlade-Chamberlain.
Gerrard told the Liverpool Echo: "In my opinion it was a stonewall penalty. It was even more blatant than the penalty which was awarded. The referee was very close to the incident. It's one you expect to get.
"Howard Webb is a top referee and I'm sure he will have a look at it himself. He obviously did not think it was a foul, but I am disappointed with the decision.
"It was a big decision that didn't go our way. That might have been the goal which would have given us a replay."
Liverpool manager Brendan Rodgers was also critical of Webb's decision after the game.
