The Danish international aced psychometric tests to show a self-belief not seen in the likes of Thierry Henry, David Trezeguet and Nicolas Anelka.
Speaking with Swedish magazine Offside, Crevoisier said: “One of the categories is called ‘self perceived competence,’ i.e. how good the player himself thinks he is. On a scale up to 9, Bendtner got 10!
“We have never seen that before. Pat Rice was sitting next to me and couldn’t stop laughing.
“When Bendtner misses a chance, he is always genuinely convinced that it wasn’t his fault. You might say that’s a problem, and to a certain degree it can be.
“But you can also view it as this guy has a remarkably ability to come back after set-backs.”
The test, which is made-up of 117 questions designed to test players' self-belief, concentration levels and determination, is used by Gunners boss Arsene Wenger to determine his players' mental abilities in relation to their footballing abilities.
Bendtner, who has claimed he will be one of the best strikers in the world within five years and when fully fit should be in the Arsenal starting line-up, has often been a controversial figure amongst Arsenal fans following his hit and miss time at the Emirates.
Fellow striker Robin van Persie, meanwhile, believes that Arsenal are still firmly in the title race going into Saturday's away game at Newcaslte United, and is confident that rivals Manchester United will drop points.
Speaking to reporters he said: “It is vital to just keep looking at yourself. We all know United’s schedule, we know Chelsea’s schedule, but the main thing is to just look at our own.
“We have got a tough opponent now at Newcastle away, and so we only need to look at that.
“I am confident Manchester United will drop points, 100 per cent, because they have big games coming up - they have their own derby, they have games against Chelsea, other big games, so we will see what is going to happen.
“We just have to stick to ourselves and I am confident we can fight until the end.”
Following his lengthy spell on the sidelines through injury, Van Persie is currently placed 1469th in the Castrol Rankings, up from 1563rd a month ago. Bendtner is ranked 328th, up from 618th the previous month.
