Former England captain Bryan Robson has "agreed in principal" to become coach of Thailand's national team, the country's soccer chief said. "Robson is interested and has agreed in principal to become our coach," Worawi told Reuters.

"He wants to come and discuss the details in person. He's a big name and we think he could play a big part in improving Thai football."

Robson has managed Middlesbrough, Bradford City, West Bromwich Albion and most recently, Sheffield United, whom he quit in Feb 2008.
