Reds defender Skrtel finished from six yards after less than a minute, before guiding a header home for his second shortly after.
We know what we’re playing for; we’re fighting for our life to get into the top four
Brendan Rodgers’ men poured forward at every opportunity and Raheem Sterling tapped in before Daniel Sturridge added a fourth before half-time at Anfield.
Sterling netted his second of the game to seal three points, before Mikel Arteta netted a consolation from the penalty spot.
And the Liverpool centre-half said the Reds were fighting for their lives to secure a fourth-place finish.
“It was a perfect win for us. We knew before the game that it was going to be tough, and it’s always special when you play big teams like Arsenal,” Skrtel told Liverpool’s website.
“We just wanted to start the game well and show we were ready for them – to be leading 4-0 after 20 minutes was perfect. We’re just happy we got three points from this game.
“We are ready. We beat Everton 4-0, we beat Arsenal 5-1 – they are big wins and big points for us. Now we have to be focused for the next game we play, on Wednesday.
“We need to get three points there as well. We’re going from game to game, trying to get as many points as we can. We’ll see where we finish at the end of the season. We know what we’re playing for; we’re fighting for our life to get into the top four.”
