Andre Villas-Boas has admitted for the first time that he could be sacked as Chelsea manager.

Villas-Boas has repeatedly insisted he retains the full backing of billionaire owner Roman Abramovich but has now confessed to the first seeds of doubt about whether he would keep his job. Speculation has been rife over the future of Villas-Boas during what is currently Chelsea's worst season since Abramovich joined the club in 2003.

In an interview with Portuguese radio station TSF which was only broadcast on Monday, the 34-year-old reiterated he felt he retained the "confidence" of Abramovich, but he compared his situation to that of Carlo Ancelotti, who was sacked in May, and he said: "We are now in the exact same moment as last year. It is an exact copy."
