4. Dan Carter
He is a free agent once again after his stint with the Blues came to an end. In April, he quit the stalled Japanese scene where he won a title for the Kobe Steelers on the back of his success in France with Paris club Racing 92. The 35-year-old played 112 tests for New Zealand, winning 99 of them and scored 1598 points which remains an international record. It’s expected he will move to Major League Rugby.
