Mourad  Boudjellal is doubling down on his criticism of former All Blacks wing Julian Savea

The Toulon rugby boss earlier this week said he wants a DNA test from Savea after his performances at the club, telling him he's "not welcome" despite having a year left on his contract.

He's been asked by French newspaper Le Parisien if he regrets his comments but he's reiterated that he finds Savea's behaviour unacceptable.

Boudjellal says he's even trawled back through the quarter-final of the 2015 World Cup between the All Blacks and France to see if it's the same player.
