Townsend, the recent hero of England's World Cup qualification, shone again with an inspirational goalscoring performance in a 2-0 win for Spurs at Aston Villa.
Villas-Boas said: "It is early beginnings for Andros with his life at the club.
"Gareth's influence grew to be immense in the last season. It is early days for Andros.
"But I think it was a great performance. Alongside the team, it grew in the second half, and he really improved his performance.
"He gives us so many attacking options because he is able to take the team forward with his driving ability and link-up play, crossing, assisting. It was another great performance, like we saw for his country. It was great to see."
