Victory at El Madrigal moved the Yellow Submarine onto 40 points in La Liga ahead of the trip to the Bernabeu at the weekend.
"First we'll enjoy this win and from Tuesday see what the week brings. Hopefully we have no mishaps. But the goal is to beat Real Madrid, and then the next opponent," he told reporters.
"If we win many more games, we'll finish high up the table. Until now we have been very smart in playing every game like a Cup final and that should remain the case.
"We should respect every opponent to the fullest with the intention of continuing to improve."
Villarreal are just three points off the top four.
