Henderson was at the heart of the memorable win.
Asked if it the best performance he has been part of since arriving on Merseyside in the summer of 2011, Henderson told liverpoolfc.com: "I think so.
"It was a fantastic performance, especially against Arsenal, who were top of the league. I'm sure they would have wanted to win the game. But our performance was fantastic and it was one of the best so far.
"Fulham are next and it will be a very difficult game. They are fighting. So I'm sure that it will be very difficult. But we've got to take this performance and this confidence down to Craven Cottage and hopefully we can do that."
