Manchester City boss Sven Goran Eriksson has the job for life, says chairman Thaksin Shinawatra.
"I didn't expect the team would achieve this kind of level. But I did believe when I arrived that Manchester City could improve a lot.
"And you simply have to hand it to Sven who has done a marvellous job."
He added: "He is a very good football strategist and he teaches the players well. His motivational ability is another important part of his game.
"We consider him as a world-class manager. There are not many of them in football but Sven is certainly one of them."
