The Portuguese boss brought in Romelu Lukaku, Juan Mata and Oriol Romeu among others during the summer break, breathing new life into the Blues' squad.
The 32-year-old is expected to see his opportunities limited this season, as Chelsea's new breed take over, and the Frenchman feels the club are in good hands.
"It's a good thing for Chelsea to have the young players come in, you still need the quality but it's a good thing," he said.
"Some of us are getting older and it is good to have the new blood. Of course you need some wise players, and we are still here, we are mixing in the same team the old generation and the new generation.
"You can't just put the young generation in and tell them they need to win. You need some older guidance, and this is what we are trying to do on the pitch. Trying to do our best and also help the young lads.
"Romelu is young and coming from Belgium, another country and way of playing, another league, so he needs to adapt. I think he speaks five languages, so it's good for him because he can adapt easily in the dressing room and learn on the pitch as he plays more games."
Anelka made a telling contribution against Manchester United, setting up Fernando Torres at the start of the second-half during his last appearance for the club, proving that he still has plenty to offer in the Blue of Chelsea.
However, Villas-Boas revealed after the game that Anelka could leave the club in the near future, however the forward isn't thinking about leaving west London.
"I am linked everywhere but when you are linked it doesn't mean you want to leave," he said.
"I like Chelsea and first of all wanted to stay, that's why I am still here. I will see what happens in December and if I am still here I will see what happens in June.
"I am happy here, I like the club, everyone here, and after I will see what happens. It is not only down to me.
"I have been here almost four years now, and I am pleased with the way it has been. It could have been even better but I am still happy."
