The eight women’s taking part in the Argentina Hockey World League Final will be represented by the best players in the world - hockey heroes and rising stars.
With all of the teams taking part in Rosario already qualified for the Rio 2016 Olympic Games, competition will be intense.
Every single game has its own history, with rivals going head to head throughout the competition as each and every one of them strive to win the coveted Hockey World League title.
The opening day will play host to one of the hottest rivalries in world hockey when reigning Olympic, World and Hockey World League champions Netherlands begin their title defence against Germany on Saturday 5 December.
Australia will be looking to avenge their penalty shootout loss to hosts Argentina in the Champions Trophy 2014 final as both teams go head to head on 6 December. Australia, ranked number two in the world, will once again have to endure the passionate support of world number three ranked Argentina in the Estadio Mundialista de hockey.
An Olympic gold medal game rematch between Netherlands and Argentina will not be possible until the quarter-finals, as would a rerun of the 2014 Hockey World Cup final and 2013 World League Final between Netherlands and Australia. Netherlands find themselves in Pool A while Argentina and Australia are in Pool B.
8 December will see the Netherlands take on Korea, with both teams playing out an extremely tight final in June's Hockey World League Semi-Final in Antwerp Belgium, which the Dutch won 2-1.
In addition to renewed rivalries, there will be many extra incentives for teams taking part in Rosario.
In addition to winning the Hockey World League title, the winners will receive an automatic qualification spot for the Champions Trophy taking place next June in London, England.
FIH World Ranking points will also be awarded depending on the teams final standings in Rosario, which will effect each team's World Ranking position. This could prove crucial when it comes to qualification for forthcoming international hockey events.
It will also be one of the last opportunities for teams to compete against one another before they meet again in Rio next August.
Not only will it give teams a chance to discover their opponents strengths and weaknesses, it also provides athletes with another opportunity to showcase their skills to their own coaches who will be monitoring player performances ahead of Olympic squad selections over the coming months.
With so many great rivalries and so much on the line, fans can expect to experience displays of exceptional skill and outstanding physical fitness, with non-stop action and plenty of goals.
