Both countries came through their semi-finals in straight sets today in Bangkok to set-up the mouth-watering finale tomorrow.

The Brazilians, who beat the US to the gold medal in London, saw off The Netherlands 25-18, 25-16, 25-23 to progress at Indoor Stadium Huamark in the Thai capital.

Natalia Pereira top scored with 13 points, with both captain Fabiana Claudino and Fernanda Rodrigues adding 11 points apiece in the victory.

It means that Brazil are warming up nicely for their home Olympics in Rio de Janeiro next month, where they will be among the big home hopes for gold in a volleyball-mad nation.

Brazil coach Jose Roberto Lages Guimaraes said: “I’m very proud of my team. 

"We really played a good match especially in the first two sets. 

"We made a lot of mistakes on reception in the beginning of the third set. 

"It’s very important for us to make it to the finals. 

"The World Grand Prix tournament is very important for us to prepare us for the Rio 2016 Olympic Games."

The US, the defending Grand Prix champions, beat Russia 25-20, 25-23, 25-14.

Kimberley Hill top-scored with 17 points in their victory.

USA coach Karch Kiraly said: “Russia have a very good programme in women’s and men’s volleyball. 

"It is a popular sport out there. 

"It’s always great to play a team with a different playing style. 

"Russia are a very good team.  

"They have height and they are good at blocking. 

"This tournament is great for us to prepare for the Rio 2016 Olympic Games. 

"There are so many tough teams in the Olympic Games - Brazil, China, Russia, Serbia, Italy and Netherlands. 

"We’re excited to play against Brazil tomorrow. 

"We haven’t seen the true Brazil yet. 

"It’s going to be great for both teams in the last tournament before the Olympic Games.”
