Two penalties from Steven Gerrard and a Luis Suarez strike saw Brendan Rodgers's men embarrass their old rivals at Old Trafford, but the midfielder refuses to get carried away.
Two penalties from captain Steven Gerrard and a Luis Suarez strike six minutes from time secured a comfortable victory for the Reds at Old Trafford and, although the result sparked wild celebrations from the away fans, Henderson is already focusing on Saturday's trip to Cardiff City.
The England international has become an integral part of Brendan Rodgers' side this season, having started every Premier League game in its rise to second in the table, and is eager to focus despite the boost of a win over United.
"We knew it was a massive game but we have been brilliant of late, and we felt as though we were capable of doing what we have been doing all season and have a really good chance of winning the game."
"We have just got to keep focused on what we are trying to do as a team, take each game as it comes and not get too carried away," he continued. "That will start again against Cardiff and we will see where we are at the end of the season."
Sunday's victory moved Liverpool to within four points of Premier League leaders Chelsea, with a game in hand on Jose Mourinho's side.
