Swing changes still causing difficulty for Rory McIlroy in France

Rory McIlroy revealed how much work he has to do before bidding to regain his Open title after an erratic opening round in the 100th French Open in Paris.

McIlroy was two under par after six holes at Le Golf National but eventually had to settle for a level-par 71 featuring four birdies, four bogeys and two trips to the water at the 2018 Ryder Cup venue.
