Former Manchester United and England captain Bryan Robson has been diagnosed with cancer.
Robson, currently in charge of the Thailand national team, has had a cancerous tumour removed from his throat and will need further treatment.
The 54-year-old, who won 90 caps for England and played 461 games for United, had an operation on March 3 to remove the tumour.
A statement released by United confirmed the news: "Bryan Robson underwent an operation to remove a tumour from his throat on March 3, 2011 in a hospital in Bangkok.
"The laboratory report revealed a cancerous tumour, which will need further treatment. The oncologist is confident that the condition is treatable.
"At this moment Bryan is fine to continue with his role as Thailand coach and his role as ambassador of Manchester United.
"Bryan and his family have requested that he can continue with his treatment in private and ask that their privacy is respected.''
Robson began his playing career with West Bromwich Albion before moving to Old Trafford in 1981 and spending 13 years there.
He finished his playing days as player-manager of Middlesbrough, who he led to the Premier League and to both domestic cup finals before leaving in 2001. Further managerial spells with Bradford City, West Brom and Sheffield United ultimately proved to be unsuccessful.
Robson moved into international management in September 2009, replacing Peter Reid at the helm of Thailand, but he failed to lead the team to the finals of the 2011 Asian Cup or out of the group stage of the 2010 AFF Suzuki Cup.
