2007 AFC Asian Cup qualification
The 2007 AFC Asian Cup qualification was held in late 2005 and the final qualification round was held from February to November 2006 with 25 nations participating.
For the first time, the defending champions (Japan), did not earn an automatic berth in the finals and had to compete in the qualification tournament. Twelve teams from top two of each groups joined with four host nations (Indonesia, Malaysia, Thailand and Vietnam) qualify for the final tournament.
16 national teams did not enter qualifying (The team's FIFA World Ranking was considered for November 2005):
Thus, out of 46 national teams, 29 entered the qualifying.
In December 2005, Bangladesh and Pakistan played off in a home and away series (with Bangladesh hosting the first leg), to determine which team would progress to the final qualifying round. This was originally scheduled in November but the earthquake in Pakistan forced it to be postponed.
After a goalless first leg in Bangabandhu National Stadium, Dhaka, Bangladesh on 22 December 2005, Bangladesh won the second leg thanks to the goal from Firaj Mahmud Hossain at the 84 minute in People's Sports Complex, Karachi, Pakistan four days later. Bangladesh qualified with the 1–0 on aggregate.
