Iranian legend Ali Daei is impressed with the development of Asian football since he started his glittering playing career.

"I think Asian football is so much better today than 15 years ago and I can attribute this to the rise in the level of professionalism in many Asian clubs," Daei told the Asian Football Confederation's official homepage.

"I think Asian football will get better in time and I hope one day we will achieve better results in the World Cup."
