Furious Thai fans have demanded the resignation of the country's soccer president and want answers as to why a side once tipped to become an Asian soccer heavyweight has stumbled embarrassingly in every competition since Robson took over.
Bad times: Robson's previous job was an unsuccessful spell at Sheffield United
The former Manchester United skipper, who replaced compatriot Peter Reid in September 2009, called his own news conference to explain the team's dire form and admitted he would not give himself a passing grade in his first national team job.
