I am adding Asian WC 2010 qualifiers and there is some confusion of Oman players. Below is the infos I have gathered, grouped by source:

ZeroZeroFootball:

[url="http://www.zerozerofootball.com/player/ahmed_hadid/current/profile/0/default/105395"]Ahmed Hadid Al-Mukhaini[/url]

From what I can understand:
- PH has mixed up the careers of Mohamed and Ahmed
- ZeroZero and National-soccer-teams have mixed up the two Ahmeds
- is it possible that the two Ahmeds are one and the same guy? Which is the correct DOB in such a case?
- if the two are distinct, can we confirm that the 1985 Ahmed played against Nepal and the 1984 Ahmed played the rest of the 2010 qualifiers?

Help will be greatly appreciated!!

According to football-lineups.com, the two Ahmed guys are the same player with DOB 18-7-1984. Can anyone confirm?

Nobody knows anything?

For the time being I will assume that there is only one Ahmed Hadid, DOB 18-7-1984. This is what most places on the net say too. If anyone confirms FIFA's information, I will split the two careers at a later point.
