Rory McIlroy has blasted LIV Golf star Phil Mickelson for his "bold" claim that the established PGA Tour is "trending downwards" following the arrival of the Saudi-funded breakaway series.
Mickelson has become a divisive figure within golf since moving to LIV, which is headed by Greg Norman.
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 when 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.
