Nicklas Bendtner's cocky attitude is well known inside Arsenal.

The young Dane scored in last night's Carling Cup victory over Newcastle United and before the match remarked: "Everything I do I always feel very confident - whether it's tennis, badminton, football, whatever. I just go out there and think I can do it and most of the time I can. What I'm good at I don't mind saying because it's not a secret, is it?

"For me confidence is so important. It's good to know I can go out on the field and feel I can take on the world."

Bendtner's attitude has not always endeared him to the staff at Arsenal - or at Birmingham during his year-long loan spell last season - since arriving at the club from Copenhagen as a 16-year-old.

"Nicklas fully rates himself. He thinks he should be in the team every game. He thinks he's better than [Emmanuel] Adebayor and he's not afraid to tell anyone what he thinks either," one Arsenal insider told the Daily Mail.
