Bale hit a hat-trick in victory over Aston Villa yesterday.
Villas-Boas said: "I think so. You always expect that the team can make an individual even better.
"The team changes so much from one year to another, and as he keeps learning, he will feel even better and probably his performances will improve.
"His finishing is very accurate. He has been prolific in front of goal this season and I think he is enjoying getting into those positions.
"His left foot is wonderful and the power and direction he applies on the ball is wonderful too."
