The former Milan coach took over at Stamford Bridge last summer, and after a string of impressive displays Chelsea suffered a sudden dip in form as the winter break approaches.

While some critics hold Ancelotti responsible for his team's loss of form, the Italian tactician stressed that he drastically improved the London side over the past months.

"I think that Chelsea have shown a new play in the last year, and shown personality and identity," the 50-year-old said.

"Sometimes we can play well. Sometimes we don't play such a good match. But every game Chelsea play with personality, with a particular system of play and, also, with a good identity.

"With Roman, I haven't spoken about this question. He will have his idea on his team."

Ancelotti mentioned in his autobiography, which was released earlier this year, that club president Roman Abramovich was dissatisfied with the lack of personality at the Premiership giants.

Although Chelsea have won a single match in their last six outings on all fronts, Ancelotti doesn't feel that his future is hanging in the balance.

"I never think that if I don't win games Roman will remove me," he said.

"My aim is to do the best for this club, as I have done for other clubs."
