10. Dan Carter (New Zealand)
There are lots of outside-halves who have been great, but not one who has done it over so many years like Carter.
9. Agustin Pichot (Argentina)
Pichot and Felipe Contepomi were the ones who helped transform Argentina into one of the greatest sides in the world. He was an architect behind their march to the World Cup semi-finals in 2007, which set the trend ahead of their excellent showing in the 2015 tournament, too.
1. Gethin Jenkins (Wales)
He rarely smiles but has been a terrific player at loose-head prop. When I’ve penalised him and he’s smiled, I know I’d got the decision right!
2. John Smit (South Africa)
He led the Springboks to success at the 2007 World Cup in France and against the 2009 Lions and is probably one of the greatest captains I have dealt with.
3. Phil Vickery (England)
I always had a lot of time for him, found him a decent man, a good player to referee. He wasn’t one of those who would whinge at decisions, he would accept the call and get on with it.
