Ban could take shine off Liverpool's romp
Gerrard in danger of missing United clash
Liverpool captain Steven Gerrard is in danger of a three-match ban after appearing to elbow Portsmouth's Michael Brown in an off-the-ball incident during his side's 4-1 victory on Monday.
The Football Association may yet take action after studying film of the clash which happened during the second half at Anfield - and it could bring a suspension that would rule Gerrard out of their meeting with Manchester United next Sunday.
Gerrard was substituted shortly after Brown was flattened in an incident that was not punished by referee Stuart Attwell, who thought it was a "coming together" between the players.
"They were asking me about it, but I didn't see it. I prefer to enjoy the game," said Liverpool manager Rafa Benitez afterwards.
Portsmouth manager Avram Grant also claimed he missed the incident.
"I was told the referee was four metres away from it," he said.
"I think he needs to see from four metres what I didn't see from 40 metres. He missed a lot of things."
Gerrard had earlier played a part in Liverpool's comfortable win against relegation-threatened Portsmouth, with the goals coming from Fernando Torres (2), Ryan Babel and Alberto Aquilani.
It keeps alive Liverpool's hopes of finishing fourth and qualifying for next season's Champions League.
It was Aquilani's first goal for Liverpool since the Italian midfielder joined from Roma for £17 million last August.
"I have waited a long time for the goal, so I am very happy," said Aquilani.
"Now we need to win a lot of games to finish in the top four."
