The Welsh ace struck a second-half hat-trick as Spurs hammered Aston Villa 4-0 at Villa Park on Wednesday and his performance gained plenty of recognition from his boss.
"He is up there with the best," Villas-Boas said.
"He is showing tremendous skills and talent, I think he is improving every day - he is such a young player - and he is helping the team. He is one of our major assets.
"His personality is wonderful, he is going through an excellent moment of his professional and personal life, and we are benefiting from that."
And Villas-Boas feels 23-year old Bale can continue to get better and better as his career progresses.
"I think so. You always expect that the team can make an individual even better," he added.
"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."
