'The best I've ever seen him swing': Jack Nicklaus tips Rory McIlroy for US Masters success

Jack Nicklaus believes Rory McIlroy is the man to beat in the Masters as he seeks to complete the career grand slam with a victory at Augusta National.

A resurgent Tiger Woods, 2015 winner Jordan Spieth, US PGA champion Justin Thomas and world number one Dustin Johnson are among the favourites for the year's first major championship.
