Chelsea boss Andre Villas-Boas believes that his job at the helm is safe despite the recent availability of ex-Blues manager Guus Hiddink.

The Dutchman, who was brought in to take over at Stamford Bridge in 2009 because Luiz Felipe Scolari was sacked after seven months, has hinted that he may be interested in a return to the former Premier League champions after leaving the Turkey national team.

"I have no problem with what has happened with Guus," The Mirror quotes Villas-Boas as saying. "I have no idea if he still advises the club. Guus had a very important period in the club, not that Scolari didn't have an impact.

"Hiddink came on board and made the necessary changes to get to another Champions League semi-final, the FA Cup and go 15 games with only one defeat.

"This was a good period for the club but it was only six months in the club. That doesn't mean he would always be successful in a club of this dimensions."

The former Porto boss is adamant that owner Roman Abramovich will not consider replacing the Portuguese manager with Hiddink.

"He's a top manager. At the moment, there's no vacancy. I'm sure that, when there's a vacancy, he'll be in contention. But it's not my understanding that there is any thought of him coming back here."

Meanwhile, Chelsea prepare to host league rivals Liverpool in London on Sunday.
