Despite featuring against Lazio in the Europa League, Lloris was told he would not be needed for Wednesday night's clash with Carlisle, with Carlo Cudicini and Heurelho Gomes called upon to make the trip north.
"He is not frustrated," said Villas-Boas.
"I don't put any kind of pressure on Hugo to start. He is more than ready to start in the Premier League, but he is up against a player who is doing more than well for us.
"In the end, what I think is that Hugo's perspective is he understands he's competing against someone who is currently the No.1."
