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. The 65-year-old, who won the FA Cup while caretaker Chelsea manager in 2009, was heavily linked with a return to Stamford Bridge in the summer, with reports claiming 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. Since leaving Turkey, Hiddink has been linked with a return to the club in an directorial capacity but Villas-Boas all but ruled that out. He also shrugged off the prospect of the Dutchman being parachuted in as manager - as he was almost three years ago when Luiz Felipe Scolari was jettisoned - should his own position come under threat. 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 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." 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. Villas-Boas' job is under no immediate threat, unlike his bank balance and ability to patrol the touchline on matchdays should the FA find him guilty of improper conduct. The Portuguese this week denied a charge over the comments he made about referee Chris Foy in last month's controversial west London derby at QPR. Villas-Boas accused Foy at the time of failing to treat both sides equally but he insisted today that did not mean he had branded the official biased. He said: "The charge implicates that I was calling him biased or questioning his integrity. I was not." Asked why he had decided not to plead his case to the FA in person, he replied: "Because I have other things to do. "I'm not worried. I understand that a charge cannot be taken lightly. "It's the maximum body of English football, and I respect that, but it doesn't mean I agree with it and it doesn't mean I have to defend it to death. "I think I am defending it to death with you, publicly. "It's not for me to go in front of a panel to talk about it. I don't have to do that." Villas-Boas also insisted he remained convinced Didier Drogba would sign a new contract at Chelsea. The 33-year-old has yet to reach an agreement to extend the deal which expires next summer and was linked this week with both AC Milan and mega-rich Russians Anzhi Makhachkala. Drogba could make his comeback from suspension and arm surgery in Sunday's crunch clash with Liverpool, although he is likely to play second fiddle to £50million man Fernando Torres once more. Torres flopped on his Chelsea debut against his former club in February but Villas-Boas was confident Kenny Dalglish's men would see a different player this time around. He said: "Fernando has, of course, picked up from last season, as you've been aware, not only with his form, physically, but also his availability in terms of movement for the team. "(He's) back to his old sharpness and goalscoring terms, so we are pretty happy with the way he's performing."
