POOL A

New Zealand -World Ranking: 8th

1976 Olympic champions New Zealand, coached by former Australian international Colin Batch, are blessed with enormous talent, supreme fitness levels and an incredible will to win. Four players - captain and star striker Simon Child, midfield veteran Ryan Archibald as well as defenders Shea McAleese and Bradley Shaw will be playing at their third Olympic Games. Interestingly, Ryan Archibalds father, Jeff, was a member of the Black Sticks squad that won the gold medal at the 1976 Olympic Games in Montreal, Canada.

Australia - World Ranking: 1st

The Australia team, selected by Head Coach Graham Reid, for Rio features 10 returning Olympians and six eager Olympic debutants ready to fight together in a bid to reclaim the gold medal that they won at the Athens 2004 Games. Led by star defender Mark Knowles - who alongside Jamie Dwyer was a member of the Kookaburras team that won gold in Athens - Australia are very much the team to beat. The 2014 World Cup winners recently claimed their 14th Hockey Champions Trophy in London, Great Britain and were the 2015 Hockey World League Champions.

Great Britain - World Ranking: 4th

Following their fourth place finish at the London 2012 Olympics, Great Britain have set their sights firmly on winning a medal at Rio 2016. Looking at their recent history, you certainly would not bet against them. There has been a steady improvement since their disappointing ninth place finish at the Athens 2004 Games, with the team taking fifth at Beijing 2008 before losing the bronze medal match at London 2012 against Australia. Team captain Barry Middleton will make his fourth Olympic Games appearance while midfield star Ashley Jackson returns for his third Games after appearing at Beijing 2008 and London 2012.

Belgium - World Ranking: 6th

Belgium have made huge strides forward over the past ten years and are now rated as one of the most feared attacking sides on the planet. The Red Lions squad for Rio contains a staggering amount of international experience, with the vast majority of the squad having surpassed the 100 international appearances mark including treble centurions John-John Dohmen and Jerome Truyens as well as double centurions Cedric Charlier, Thomas Briels, Felix Denayer and ace striker Tom Boon.

Spain - World Ranking: 11th

Spain may have dropped down the FIH Hero World Rankings in recent years but they remain a gifted team that should not be underestimated. Under the stewardship of Head Coach and former France international Frederic Soyez, a talented new generation of Red Sticks players are working hard in a bid to return Spain to an era of greatness that culminated in an Olympic silver medal at the Beijing 2008 Olympic Games. David Alegre, Roc Oliva, Sergi Enrique, Miguel Delas, penalty corner ace Pau Quemada and brilliant goalkeeper Quico Cortes bring masses amounts of world level experience to the table.

Brazil - World Ranking: 30th

The host nation may be the lowest ranked team in the mens competition, but they are very much here on merit. Set the target of achieving a top six finish at last years Pan American Games in Toronto by both the International Olympic Committee (IOC) and the International Hockey Federation (FIH), Brazil went one stage better, reaching the semi-finals to guarantee a top four finish at the event. Their squad includes two players who were named in the 2015 Pan American Elite teams - striker Matheus Borges and defender Stephane Vehrle-Smith.

POOL B

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

The Olympic champions of 2008 and 2012 are always capable of winning every tournament they enter, and have set themselves the target of making it three in a row at Rio 2016. The squad chosen by Head Coach Valentin Altenburg contains five Olympic gold medallists from London, inclduing two winners of the FIH Mens Player of the Year Award. Midfield star Tobias Hauke (2013) and former midfielder turned defender Moritz Frste (2012) - both double Olympic gold medallists - are rightfully considered amongst the best players in the history of German hockey and will be central to Die Honamas title challenge.

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. Raghunath and Rupinder Pal Singh are a constant threat at penalty corners.

Ireland - World Ranking: 12th

By qualifying for Rio 2016, the Green Machine sealed their place in sporting history as they became the first Irish team, in any sport, to qualify for the Olympics since the 1908 Games in London. The team coached by former South African international Craig Fulton, the FIH Hockey Stars Coach of the Year 2015, have set their sights on reaching the quarter-finals, and judging by their remarkable bronze medal at last summers Unibet EuroHockey Championships, they are certainly capable of achieving that. 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. Their rivalry with Pool B opponents Argentina is the stuff of legend, with the two nations contesting every major Pan Am final since 1975. They have also competed at six Olympic Games, five Hockey World Cups and five Commonwealth Games to date. Scott Tupper, Mark Pearson and Matthew Guest are star performers outfield while goalkeeper David Carter is rapidly gaining a reputation as one of the finest shot-stoppers on the planet.

The Olympic hockey events take place from 6-19 August at Rios purpose-built Deodoro Olympic Park, and will feature the 12 mens and 12 womens international teams that qualified through the Hockey World League and Continental Championships.
