Thailand draw on Robson debut
Playing in torrential rain, Thailand dominated throughout but went behind to Raja Rafe's 34th-minute penalty.
Teerathep Winothai made amends for missing an earlier spot kick when he converted a header to equalise on 59 minutes.
"It was a good match today. We were unlucky but we came back very well especially in the second half where we controlled most of the game," Robson told reporters.
