Steven Gerrard will not be subject to disciplinary action from the FA as a result of his alleged gesture at referee Andre Marriner.
Gerrard appeared to flick a V-sign at Marriner after being booked for a foul on James McCarthy in a 1-0 defeat to Wigan on Monday night, but the FA confirmed the match official had seen the incident at the time, meaning retrospective action cannot be taken.
Manager Rafael Benitez said after the game he had not seen the incident and after reviewing it on video believes there was no case for Gerrard to answer.
"Sometimes you move your fingers," Benitez said. "It was nothing. We are not considering it, it was nothing. All the players know they have to behave on the pitch. I was more worried about the silly fouls we were giving to Wigan.''
Liverpool are struggling to claim fourth spot after losing a game many expected them to win, and Wigan chairman Dave Whelan was critical of the club following their surprise victory, describing the tenure of owners Tom Hicks and George Gillet as "a mess".
That drew an angry response from Benitez, who urged the Wigan supremo to keep his attention on the affairs of his own club.
"I do not know what is going on," Benitez said. "I do not talk about Wigan. I prefer to concentrate on my team. He (Whelan) should talk about his own club.''
Benitez is glad to have an opportunity to get back to winning ways quickly as they face Lille in the Europa League on Thursday, with the Liverpool boss hoping the Wigan result proves to be just a blip.
"We had been working well in the last ten games, more or less," he said. "Sometimes these things happen. Now we have to move forward. Hopefully there will be a reaction in Lille. This is an opportunity to put things right and try to get a good result.
"In football you sometimes prefer to rest but at this time it is good to have a match quickly after what happened at Wigan.''
