Shame on you!!!!
How can you report this to the world!!!!!
".....continued to argue with officials."
the Thailand coach just need the explanation from officials!!!!!
Here some word form FIVE website
"The fifth set, by any measure, was one of the most incredible sets of volleyball most fans will ever see.

Thailand had the match, and possibly a ticket to Rio, wrapped up at 9-3. But what unfolded next was one of the most amazing self-destructions in sport.

With all the momentum, the Thai team and their coaching bench somehow managed to concoct a way to lose the unlosable set.

The ill-discipline brought with it a heavy price for Thailand; the first red card came when they were leading 12-7. But instead of concentrating on sealing the game, the team became distracted and continued to argue with officials.

The second red card was inevitable; it came when Thailand was trailing 12-13, and virtually gifted the match to Japan."
