do u know who'll host the qualification tournament in Asia ? i think this can also play a rule , from Wikipedia they say 4 countries are interested Australia and Vietnam are among the list , well apart from Korea and Japan it's always hard to find the 3rd team in Asia who'll join them now we have 2 other spots so it'll be a great battle for other 2 quotas , Iraq always delivers very good U23 teams , i always believe in Iran in Asia , KSA has some good talents at this age category and they proved it in U20 , Qatar always buying players and they're much focusing now on bringing young talents especially from Africa in Aspire Academy , they have been the best team by far at the last U23 tournament , they only had some hard luck against Vietnam IMO , Uzbekistan always has a shot , the host especially if it's awarded to Australia or Vietnam , well u can't predict clearly in football when it comes to olympics , but i think Korea , Iran and Qatar will qualify this time
