Luck Loser

Pong is one of the greatest football players Thailand has produced and he's a star in England's FA Premier League. But when there's an opening for coach of the Thailand national team, Pong returns in hopes he'll be named for the job. Instead, he is passed over in favor of a Brazilian coach.
His Aunt Ming, a football fan and inveterate gambler, has just won the lottery and had intended on donating her winnings to the Thai team. However, when her nephew is passed over, she decides to give her money to a regional rival, the struggling team in neighboring Arvee. And she's able to convince the team officials to hire her nephew.
So Pong is named coach of the Arvee side.
