Chelsea boss Andre Villas-Boas insists he is not feeling the heat at Stamford Bridge - despite the club's recent slump.
The Blues made a storming start to the season, but have won just one of their last four matches, suffering back-to-back league defeats against QPR and Arsenal.
While Villas-Boas can cite two red cards in mitigation for the QPR loss, Chelsea looked shambolic in defence against Arsenal, giving away five goals - and produced a listless performance in their subsequent game, away to Genk in the Champions League.
Chelsea's attacking mentality this season is believed to be at the insistence of owner Roman Abramovich, and Villas-Boas says the Russian has been happy with performances.
"I have had conversations with the owner and they have been very supportive," Villas-Boas said. "Our responsibilities are to win every game. When things don't go our way, we can't be happy. But this week the results we have been getting haven't matched our confidence.
"There's a good spirit in the group. The owner is happy with our attacking philosophy, but we won't avoid our responsibilities to win titles. We will defend this philosophy to the death, but what is expected of us is to win titles."
Brazilian defender David Luiz has been singled out for criticism following a series of errors, but Villas-Boas will not move the player - a fine technician - into midfield. "I don't believe the assessment that Luiz is not a natural centre-half," Villas-Boas said. "Brazil have the most world titles so, when a player plays for the side in the world with the most titles, that says it all."
