The practice of professional rugby players changing their nationality (in most cases from their nation of birth) to play international football has been in action for many decades now.
This list includes eight interesting cases of players who have represented more than one country.
#1. Martin Johnson - England/New Zealand
As a player, he famously led England to glory at the 2003 Rugby World Cup and also captained the British & Irish Lions in 1997 and 2001 - the only player to have ever led the elite tourists on two occasions.
However, what you might not know is that All Blacks legend Colin Meads invited the raw but promising teenager to New Zealand to play for the King Country province in 1989 and Johnson, who took up the offer, would go on to be capped by New Zealand U21s.
#2. Pat Lam - Samoa/New Zealand
New Zealand's loss was Samoa's gain in the case of back-rower Pat Lam, as he traded All Black for the blue of the Islanders after failing to win a Test cap. He played only once for the All Blacks, in a 1991 tour game, but won 34 caps for Samoa and played at three World Cups.

2. Billy & Mako Vunipola (Wales)
Mako Vunipola, far-right in the back row, and Billy, fourth right, played for East Wales schools alongside Wales’s Taulupe Faletau. However, after attending English schools they made the switch to represent England. Billy even once admitted he wanted Australia to win the 2003 Rugby World Cup.
4. Va'aiga Tuigamala - New Zealand/Samoa
Widely known as 'Inga the Winger', Va'aiga Lealuga Tuigamala is also known as being one of the most powerful, hard-hitting and versatile backs ever to play the game.
As well as representing the All Blacks at international level, Inga also played for Samoa in both rugby union and rugby league both at centre and on the wing. As an All Black, he played in 19 tests (scoring 5 tries) and 20 non-international matches (scoring 9 tries).
5. Brad Barritt - South Africa/England
Despite playing for the emerging Springboks, South African-born Brad Barritt went onto represent England after moving to Saracens.
