Andre Villas-Boas has seen his Chelsea side suffer mixed results at the start of the season
Manager Andre Villas-Boas says Chelsea's confidence has not been dented by their recent run of poor form.
The Blues travel to Blackburn Rovers on Saturday after back-to-back defeats against QPR and Arsenal - and with disciplinary problems to deal with.
In-form Barclays Premier League leaders Manchester City are looking strong and Chelsea need to avoid a repeat of last year's costly mid-season slump if they want to challenge for the title.
Boss Villas-Boas admits things have not been easy, but insists the Blues will overcome their problems.
"This week that has passed, and the results we have been getting, doesn't hurt our confidence," he said. There's a good spirit in the group. There's a negative momentum we are passing by.
"We want wins as soon as possible. We went past a bad period and bad momentum last year, and we want to avoid that again. The memory of that is bad enough to not want to repeat it. But we're not questioning our quality or our talent."
Chelsea have had particular troubles in a defence which collapsed spectacularly against Arsenal, conceding five times in the remarkable 5-3 defeat at Stamford Bridge.
But Villas-Boas said he retained complete belief in the quality of his squad.
"We are not satisfied with the way we are conceding goals, but we are looking to score more goals than our opponents," he said.
"Our defensive organisation is solid, is competent, and we have complete trust in it."
