Australian winger Nick Cummins, whose nickname is 'The Honey Badger', offers advice on marking Wales wing George North.
Cummins will not be playing for Australia against Wales in Saturday's autumn international because he plays in Japan, while Northampton's North will be playing out of position at centre.
Cummins, who has been capped 15 times by the Wallabies, gives a colourful insight into facing North as he spends a week in the UK as a member of the Barbarians squad.
Watch the full interview with Nick Cummins on Sport Wales on Friday, 7 November at 19:00 GMT on BBC 2 Wales.
