Robbie Manson expects his status as New Zealand's premier men's single scull rower to be challenged again before the Olympics

Manson has earned the nod for this international season, over two-time Olympic champion Mahe Drysdale.

Drysdale has vowed to come again for the spot, but Manson says he has to focus on a strong campaign abroad.

He says he wants to get that right and enjoy the process this year as well as qualify the boat for the Olympics.
