Sir John Kirwan's Blues regime has received another knock, with a key player backing away from endorsing his coaching credentials.
Departing All Black back Charles Piutau shied away from saying Kirwan should stay at the helm, when interviewed by Newstalk ZB's Tony Veitch.
Veitch asked the 23-year-old if he had full confidence in the coach. Piutau replied: "Oh, I think you know...I can't really speak on that. I'm not too sure. Whatever the board and franchise decide will be the best for the team. I'll back that."
When Veitch asked if Kirwan had the goods to coach at Super Rugby level, Piutau said: "That's a tough question...I don't want to comment."
