Rory McIlroy has admitted his relationships with a number of Ryder Cup team-mates who have jumped ship to LIV Golf have become increasingly strained.
Ahead of what could be a tense week at the BMW PGA Championship, plenty of the talk has once again been dominated by the controversial LIV Golf series - with a total of 17 of its members competing at Wentworth, the home of the DP World Tour.
And four of McIlroy's European Ryder Cup team-mates from their drubbing at Whistling Straits are competing at Wentworth this week - including Ian Poulter, Lee Westwood, Sergio Garcia and Bernd Wiesberger.
