Thomas Tuchel admitted he is aware of Chelsea's ruthlessness when it comes to sacking managers but insisted it does not scare him.
Tuchel was thrust into his first game as Chelsea boss on Wednesday night against Wolves, which the Blues drew 0-0, 24 hours after he was confirmed as the permanent successor to Frank Lampard at Stamford Bridge.
When asked about whether he is concerned by the club's culture of sacking managers Tuchel, speaking at his official unveiling press conference, Tuchel said: "Yes and no.
"I am absolutely grateful that I can work on this level. If you sign up for Chelsea you sign up for the hunger of titles. You sign up for being competitive in every competition that you play. I am aware of that.
"It does not scare me [to be sacked]. We have big ambition, and I myself have the biggest ambitions. I am excited about the structure of the club. I am absolutely aware at some point everybody expects results, but I expect that of myself.
"It was an opportunity with one of the biggest clubs in the world in the most competitive league in the world. We felt like we should absolutely not miss the chance to join the Chelsea family. It was a pretty easy choice."
Club owner Roman Abramovich is not inclined to show mercy when it comes to underperforming managers, having now said goodbye to 14 coaches, including Jose Mourinho twice, since his arrival in 2003.
