Netherlands -World Ranking: 2nd
Current European champions and Olympic gold medallists from 1996 and 2000, the Netherlands have a squad containing a glittering array of world class talent. Their leading light is 2015 FIH Hockey Stars Player of the Year Robert van der Horst, while rapid striker Jeroen Hertzberger, skillful playmaker Billy Bakker and powerhouse defender turned penalty corner expert Mink van der Weerden are all hugely influential figures. In-form and with plenty of firepower, the silver medallists from London 2012 are genuine contenders for the gold medal.
Germany - World Ranking: 3rd

Argentina - World Ranking: 7th
Over the past two years, 2015 Pan American Games winners Argentina have developed into a side that can challenge the very best in the world.Head Coach and former Argentina international Carlos "Chapa" Retegui - the man who, remarkably, guided both the men and the womens national sides to bronze medals at the Rabobank Hockey World Cup - is overseeing? the revolution, helping Los Leones (The Lions) to realise their massive potential. Key players include veteran captain Matias Paredes, defender Pedro Ibarra and creative genius Lucas Vila, although it is drag-flicking defender Gonzalo Peillat who often grabs the headlines.
India - World Ranking: 5th
Eight times Olympic champions India - coached by legendary Dutch tactician Roelant Oltmans, the man who guided the Netherlands men to Olympic and Hockey World Cup glory in 1996 and 1998 respectively - have been in outstanding form this year, claiming silver medals at the Sultan Azlan Shah Cup (Ipoh, Malaysia) and the Hero Hockey Champions Trophy (London, Great Britain). Their squad is packed full of immense talent. Team captain P.R. Sreejesh is one of the most gifted and charismatic goalkeepers around, while drag-flicking defenders V.R.

Ireland - World Ranking: 12th

Key players include FIH Hockey Stars Goalkeeper of the Year 2015 Davey Harte and midfielder Shane ODonoghue, who averages a goal every two games for his country.
Canada - World Ranking: 15th
Canadas Red Caribous have long been a major force in Pan American hockey, having claimed a glittering collection of medals from the Pan Am Games and Pan Am Cup competitions.
