Robson set to take Thailand job
If the deal went through, the former Manchester United midfielder would be tasked with steering the team to the 2014 World Cup finals, Football Association of Thailand (FAT) president Worawi Makudi 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, 52, would replace fellow former England international Peter Reid, who parted company with the Thais on September 9 after less than a year in charge.
Reid's lucrative contract, reported to have been worth close to $1.6 million a year and part-funded by the English FA, was terminated by mutual consent.
The FAT rejected his request to coach the Thai side while serving as assistant manager at Premier League Stoke City.
Robson has managed Middlesbrough, Bradford City, West Bromwich Albion and most recently, Sheffield United, whom he quit in February 2008.
