Liverpool manager Brendan Rodgers was left bemused as to why Luis Suarez was not awarded a second penalty in their 2-1 defeat to Arsenal.
With the Gunners looking in command, Suarez was tripped by Lukas Podolski and awarded a spot-kick which Gerrard converted.
Shortly after, he was taken down again but referee Howard Webb opted not to point to the penalty spot for a second time.
"Going forward we were a real a threat and (we) are bitterly disappointed not to get something and not to get another penalty, which I though was a blatant penalty," Rodgers told BT Sport.
He added: "It was probably more clear and blatant than the first. I'm not sure because just after the first but it was certainly a clear penalty."
Arsenal had taken a two goal lead through Alex Oxlade-Chamberlain and Lukas Podolski, however Rodgers argued that his side should have probably opened the scoring.
"I thought the best team lost," he said. "I thought the very least we deserved was a replay.
"We probably should have been 2-0 up inside those first six or seven minutes. Going forward we were outstanding. I'm disappointed with the goals, the first one in particular was just a long ball into the box."
Liverpool, who are currently fourth in the Premier League, are still in with a chance of winning the Premier League and this is where Rodgers says his team must now focus.
"Now we have got one competition to focus on for the rest of the season and have to really focus on these last 12 league games."
