Manchester United legend Bryan Robson has spoken of his time as Thailand coach.

Robson left his ­management job in ­Thailand because he felt he was "hitting my head against a brick wall".

Robson spent two years as national team manager, taking over from old pal Peter Reid.

He told the Sunday Mirror: "I spent two years trying to build a coaching structure but ­nothing ever moved ­forward.

"In England we've had the McDonald's scheme for ten years, creating coaches at every level of the game. When I passed my Pro ­Licence I think there were barely 100 with the ­qualification. Now there are around 2,000.

"I wanted to put that sort of structure into Thailand.

"They thought that if you just worked with the top ­players for a week before a game they would get better.

"But the real work has to happen every day at their clubs. I just felt I couldn't take things any further there."
