Rory McIlroy has hit out at LIV Golf star Phil Mickelson for his bold claim that the established PGA Tour is "trending downwards" following the inception of the Saudi-funded breakaway series.
Mickelson has become a divisive figure within golf following his move to LIV and his quotes surrounding the series, which is headed by Greg Norman.
And the six-time major champion made the headlines once again last week ahead of LIV's penultimate event of its maiden season in the Saudi city of Jeddah. He spoke about the breakaway circuit's success while aiming a dig at the PGA Tour, where he has played most of his professional career.
