The 18-year old midfielder has appeared just once in the Premier League so far this season following the summer arrivals of Juan Mata and Raul Meireles but that doesn't mean he will not be a top player for the club down the track.
"We didn't have as many competing in midfield last year, so Josh had more chances to be in the team," Villas-Boas said.
"I've just been choosing others. But that doesn't mean Josh's future wouldn't be at Chelsea. It will be."
