The Toffees lead their near-neighbours by five points in the Barclays Premier League and a first league victory at Anfield since 1999 would ensure they finish above their rivals this season.
However, Pienaar believes they are more focused on hauling in fifth-placed Tottenham, who occupy the remaining European spot with a game in hand, three points ahead.
"The most important thing is to get into Europe," he said.
"I know at this stage it is difficult but we just want to win the games and see how far we go.
"You don't know what is going to happen on top of us. Maybe one of the teams can lose all their games and we win all ours.
"We just want to win the games that are left."
The South African added on evertontv: "Derbies mean a lot and we know what's at stake.
"For the people of the city and the pride of the club it's one of those games you don't want to lose.
"We will give everything to make sure we come away from Anfield with three points because it has been a long while since we won there."
