In other action, Peter Reid's Thailand ground out a respectable scoreless draw in Bangkok with Ali Daei's formidable Iran.
Iran were expected to take all three points after running riot in a 6-0 drubbing of Singapore in their opening qualifier, but the Thais proved their match and now have four points from their two Group E games.
