Jose Mourinho brushed off further questions over his future and insists Chelsea’s troubles are not his sole responsibility.
The Blues have made their worst ever start to a season under Roman Abramovich’s ownership and must avoid defeat to Porto tomorrow night to remain in the Champions League.
Abramovich sanctioned a vote of confidence for the beleaguered boss at the start of October but Chelsea’s results have not improved since the public backing of the Russian.
Saturday’s shock defeat to Bournemouth was the defending champions’ eighth Premier League loss but the Portuguese supremo believes his track record speaks for itself.
"This is not a one-man responsibility," Mourinho said.
"There are no ifs. Wins, draw, or lose. I am an optimistic guy. There are no ifs.
"I did lots of good things in this club for the owner to know the quality I have. And if the owner shows me that belief twice - one when he brought me back to the club, the second time when he gave me a new contract, for four years - I don't think the owner is a person to change with the wind.
Chelsea training ahead of Porto clash in pictures:
"I know the wind with the results is an important wind. I know this wind is really strong, because the results in the Premier League are really bad, but I think the owner knows who I am, what I gave to the club and the owner believes I am the right person to do the job.
"Now I don't speak about the owner. I speak just about the reality of the situation. You can read these bad results and focus everything on the manager.
"You can look at the results and look to players with performances below acceptable.
"You can look to this and look to the unlucky decisions that we are having in every competition, not just the Premier League.
"You can look in many directions and you can decide."
Mourinho was pleased to receive the support of former Manchester United manager Sir Alex Ferguson, who on Monday said Chelsea would be "foolish" to sack the Portuguese.
"I didn't read. I didn't watch. Some people told me (about it)," Mourinho said.
"It's the difference between the friends and the fake friends. Sir Alex is my friend. Obviously the words are very nice. He's not the kind of person who says just because he likes somebody.
"He's always honest in his analysis and I thank him."
With Dynamo Kiev expected to beat Maccabi Tel Aviv, Chelsea would finish top with a win, second with a draw and third with a defeat, plunging into the second-tier Europa League.
Captain John Terry is fit following an ankle injury, while midfielder Ramires is also available. Radamel Falcao returned to training but is still a couple of weeks away from a comeback.
