Chelsea boss Andre Villas-Boas accepts sack talk is inevitable for him.
"When results like this happen, the head of the manager is called for execution," he said.
"I'm not worried by the comments.
"I want to get my team back to winning ways, and we'll try and do that against Leverkusen.
"As we enter a run of results, the negative spiral that this team went through last year, we don't want to go into a similar run of nine games.
"We can turn the results round. The emotions that these people lived last year are enough to make people to want to avoid that stigma this time."
