Hiddink left his position as Turkey head coach by mutual consent two days ago following the country's failure to qualify for the European Championships.
Villas-Boas said of Hiddink's current status as a free agent: "I have no problem with it."
Hiddink was only in charge of Chelsea for three months, losing just one Barclays Premier League game and a controversial Champions League semi-final on away goals.
"This was a good period for the club," said Villas-Boas. "That doesn't mean he could always be as successful as that in a club of this dimension.
"But Guus is one of the best managers in the world. At the moment, there's not a vacancy. When there's a vacancy, I'm sure that he'll be one of the top candidates."
The 65-year-old won the FA Cup while caretaker Chelsea manager in 2009 and reports in the summer claimed he was Roman Abramovich's number one choice to replace the sacked Carlo Ancelotti.
The job went instead to Villas-Boas, who the Blues have repeatedly insisted was their primary target all along.
Hiddink, who is close to Abramovich and has reportedly advised the Russian in the past, may be more interested in a sporting director-type role.
"It's not structurally even thought about within the club," said Villas-Boas, who had "no idea" whether Hiddink continued to advise Abramovich.
