Arsene Wenger admits he will always question himself as he looks to bring success back to Arsenal.
The Frenchman is facing one of the biggest tests of his 16-year tenure this season following the Gunners' Capital One Cup defeat at Bradford this week on the back of indifferent form in the Premier League.
Arsenal chief executive Ivan Gazidis has apologised to supporters for the recent setbacks and fans' groups say he pledged to make "significant funds" available to Wenger to strengthen the squad in January.
Wenger has long championed the club's drive to emulate their successes of the past by living within their own means after moving from Highbury and speaking prior to the midweek defeat to Bradford, he told fourfourtwo.com about the demands on him to succeed.
"You can only be successful if you question yourself, because the game has become bigger and better. With teams like Chelsea and Man City coming in, I think we have to do what we do even better," Wenger told the website.
"You can only be good in life if you do what you believe is right.
"We have always managed the club with its own resources, given a chance to young players and developed a style of play that we think is right. After it works, it gives us a consistency at the top level that develops a sense of trust.
"We may have a lack of experience in winning trophies recently, but we are always at the top and very close to winning the championship or winning the Champions League."
Former Arsenal defender Martin Keown - who was part of the Gunners' Invincibles team which won the Premier League title in 2003/2004 without losing a match - is confident Wenger remains the man to turn things around.
"It's about growing the players you've got, making the necessary signings in the future and certainly Arsene Wenger is the man for that," Keown told BBC Sport.
"He's going to find out a lot about himself in this difficult period but he's a winner, a fighter and he'll come back stronger from this."
Majority shareholder Stan Kroenke, meanwhile, has been criticised by former Arsenal director Lady Bracewell-Smith.
She wrote on Twitter: "[Kroenke] shows he cares very little. Why he wanted to be part of AFC I do not know.
"Football is a business of passion. SK has no passion for AFC.
"If making money was the motivating factor, surely there are better ways."
Arsenal will look to kickstart their Barclays Premier League campaign at struggling Reading on Monday night, where contract rebel Theo Walcott could return from injury.
