Arsene Wenger has never been a good loser and does not intend to start now.
The Frenchman takes his Arsenal side to north London rivals Tottenham on Saturday looking to maintain their unbeaten start to the new campaign.
Wenger last week signed a new three-year deal with the Gunners, whom he brought a period of unprecedented success following his arrival just over a decade ago.
However, Arsenal - who reached the Champions League final in 2006 - have not won a trophy for the past two seasons.
For Wenger, the hunger to deliver more silverware burns as strong as ever.
Tottenham sporting director Damien Comolli worked alongside the French coach at Monaco, and revealed Wenger possesses a "cauldron of rage", unable to sleep or eat after experiencing defeat.
Wenger challenges anyone to show him someone who is not "hurt" when their side lose.
The Arsenal manager declared: "Somebody said 'every victory slides over you, and every defeat stays overnight with you'. You find it is easy to live with what you have won, but much more difficult to live with what you have lost and not won.
"I read somewhere that I take defeat in a difficult way, but how else can you take it?
"I am never in good health after losing a game. Your emotions are linked with your health, of course.
"You should not be in this job unless it really hurts you to lose a match.
"If it does not hurt you then you will not survive in this job - and the players are the same."
Wenger added: "You have always room to think you can do better and improve - more championships, the Champions League. We could have won them both 10 times, but we did not do it, so we can only think we have to do better.
"That is the target you have to set to yourself, the club has gone a level up, and you want to be successful on every front.
"You cannot be happy if you know you have not done your best.
"I have met many people who had lots of talent, as much as Thierry Henry or (Dennis) Bergkamp, but they never did anything at all.
"I am sure everyone knows people at school who, 10 years later, have done nothing with their lives."
