World Cup winner Dan Carter concedes that the transition to Top 14 club Racing 92 has not been as seamless as he would have liked.
After more than a decade at the Crusaders, where he won four Super Rugby titles, Carter has decided to spend the final years of his career playing in the Northern Hemisphere, having retired from international rugby.
Even with all the experience he has, the change has taken some getting used to.
Following his first training session with Racing 92, Carter tweeted: "I didn't really know what I was doing half the time."
Nevertheless the All Blacks pivot has previously indicated that he was delighted to embark on this new adventure, amidst speculation that he has secured the richest club contract in the history of the sport.
His first assignment will be a fixture against Northampton in a fortnight in the Champions Cup.
