POOL C:

JAPAN: Should really excel at Sevens although they have no great track record in the game. Tongan-born Lemano Lemeki is a powerful, stepping, runner who can break most defences and Kenki Fukuoka was a member of their World Cup squad at RWC2015. With RWC2019 and the 2020 Olympics on the horizon Japan will be well motivated and although unlikely to progress have an upset win in them.

Key man: Lemano Lemeki GREAT BRITAIN: Potentially strong with a clutch of Celts augmenting the England squad that ‘qualifed’ GB in the 2014-15 World Series. A number of minor tournaments recently have served GB well in the teambuilding and selection. Scotland's Mark Bennett and Mark Robertson add to GBs firepower as does Wales James Davies while Dan Norton and Marcus Watson are well established fliers from England.

Key man: Tom Mitchell KENYA: Wildly unpredictable team who have also suffered from off-the-field disputes but, make no mistake, when Kenya are on song they can beat anybody. Consistency is their big issue, they need to produce six stand out performances to medal. Veterans Collins Injera – a try scoring machine – and his brother Humphrey Kayange are still pulling the strings along with captain Andrew Amonde.

Key man: Humphrey Kayange NEW ZEALAND: Once appeared unbeatable but more vulnerable in recent seasons although rest assured veteran coach Gordon Tietjens will have them firing in Brazil. Bank on World Cup winner Sonny Bill Williams, left, on bringing his full bag of tricks to the party while the Ioane brothers – Akira and Rieko – can both be devastating runners. DJ Forbes is still there to provide the experience. Key man: Sonny Bill Williams
