New Zealand World Cup-winning great Dan Carter says he's been enjoying working with Ronan O'Gara.

The fly-half, who joined France's Racing Metro last Autumn after his heroics at the tournament, joined Off The Ball's Ger Gilroy for an in-depth chat about his brilliant career. 

"It's really good. It's only been three months but I've been impressed with his coaching so far. He's still pretty new into coaching, he's still a very young coach, so he's learning how he's going but he's got a great drive and  a great rugby knowledge and I'm sure a really bright future, so my old rival is now my coach and I'm really enjoying getting to know him outside of rugby," he said.

The 34-year-old also spoke about the Six Nations and although he admits that it's not the most entertaining style of rugby to watch, he feels the Northern hemisphere teams will get better as the tournament progresses because they will have more time together on the training ground.

"But what I love and have learned since being here is how much it actually means to the players and the countries playing in it. There's no room for error. You only get one shot at your opponent and you don't want to muck it up, so it's extremely demanding and really intense."

Carter also spoke about how the All Blacks learned from their mistakes and instilled a new philosophy revolving around humility on and off the rugby pitch, including the "sweeping the sheds" tradition.

"If we're playing at the Aviva, Twickenham, wherever, before we leave the changing sheds, we make sure that we leave it spotless, just like it was when we walked in there. So it's just one of the traditions that we've had and it brings a lot of humility to the group," he said, before touching on the "no d***heads rule" which helps to maintain a team mentality and keep everyone grounded.
