Villas-Boas is sure it will only be a matter of time before the young centre-half will be wearing the Three Lions of England on a regular basis.
"I think for Steven it will be a privilege to play for the first team of England, for sure," the Spurs head coach said.
"If it came sooner it would be a more important achievement, but I don't see (him being left out) as any kind of negative.
"We certainly believe a lot in the player. That's why we decided to extend his career and that's why he played at Old Trafford and against Lazio.
"I think he is showing exactly the competence and the talent that he has and he will triumph in the future."
